testing capabilities Creep Test A Creep Test measures how a material deforms over time when subjected to a constant load and elevated temperature. Unlike standard tensile or hardness tests, which provide immediate property data, creep testing evaluates a material’s long-term behavior under sustained stress . This test is especially important for fasteners used in high-temperature environments, where even small amounts of time-dependent deformation can lead to joint loosening, dimensional instability, or failure. How the Test is Performed Specimen Preparation – A fastener or representative sample is prepared and mounted in a creep testing machine. Constant Load Application – A steady load, typically a percentage of the material’s tensile strength, is applied. Elevated Temperature Exposure – The specimen is heated to a defined service-relevant temperature and maintained throughout the test. Monitoring Deformation – Elongation or strain is continuously measured over an extended period (ranging from hours to months). Data Collection – The rate of deformation and time to failure (if it occurs) are recorded and analyzed. Why It is Performed Creep testing is performed to predict how materials and fasteners will behave under long-term service conditions , particularly in environments involving high heat and sustained loads. This ensures that components will not gradually deform or fail in ways that could compromise equipment safety and reliability. Evaluates time-dependent deformation at elevated temperatures Predicts service life under continuous stress Verifies material and heat-treatment suitability Prevents dimensional changes or joint failures in critical applications Application to Engineered Fasteners Engineered fasteners often operate in turbomachinery, aerospace engines, nuclear reactors, and energy systems , where they are exposed to both constant loads and extreme temperatures.

testing capabilities Eddy Current Testing (ET) Eddy Current Testing (ET) is a non-destructive testing (NDT) method that uses electromagnetic induction to detect surface and near-surface flaws in conductive materials. When an alternating current flows through a coil, it creates a magnetic field that induces circulating currents (eddy currents) in the test material. Disruptions to these currents caused by cracks, corrosion, or changes in material properties are measured and displayed, revealing potential defects. How the Test is Performed Preparation – The fastener or component is cleaned to remove dirt, grease, or coatings that might affect results. Coil Excitation – A probe containing a coil is energized with alternating current, generating a magnetic field. Induction of Eddy Currents – As the probe is placed near the conductive material, eddy currents are induced within the component. Disruption Detection – Any discontinuities, such as cracks or changes in material thickness, disrupt the flow of eddy currents. Signal Analysis – Variations in the currents are detected by the probe and displayed for interpretation by skilled inspectors. Documentation – Results are recorded to verify compliance and provide traceability. Why It is Performed Eddy Current Testing is performed because it is fast, highly sensitive, and effective for detecting surface cracks, corrosion, and material variations without damaging the part. Unlike some other methods, ET requires minimal surface preparation and can often be performed quickly on complex shapes, making it well-suited for fasteners and precision components. Detects cracks, corrosion, and material inconsistencies Can measure conductivity, hardness, and coating thickness Provides rapid results without the need for couplants or extensive cleaning Application to Engineered Fasteners For engineered fasteners, ensuring surface integrity and consistent material properties is critical. Fasteners must endure heavy loads, vibration, and environmental exposure in industries such as aerospace, energy, and defense. A surface crack or metallurgical inconsistency can lead to early failure in service. By applying Eddy Current Testing, TSP Manufacturing ensures: Detection of surface cracks and flaws before components enter service Verification of proper material properties and heat treatment Consistency in quality across high-volume production runs Confidence in the long-term reliability of safety-critical fasteners Standards & Compliance TSP Manufacturing performs Eddy Current Testing in accordance with ASTM, ASME, and industry-specific standards , as well as customer-driven requirements.

testing capabilities Magnetic Particle Testing (MT) Magnetic Particle Testing (MT) is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials, such as steel and iron alloys. The process relies on magnetizing a component and then applying fine magnetic particles. These particles gather at areas of flux leakage caused by defects, making cracks, seams, laps, or inclusions visible to inspectors. How the Test is Performed Preparation – The fastener or machined component is cleaned to remove oil, grease, and debris. Magnetization – A magnetic field is applied to the part, either directly (passing current through the component) or indirectly (using a magnetic yoke or coil). Application of Magnetic Particles – Fine iron particles, either dry or suspended in liquid, are applied to the surface. Indication of Defects – If a discontinuity is present, it distorts the magnetic field, causing particles to cluster at the flaw. Inspection – Inspectors examine the part under visible light or ultraviolet light (if fluorescent particles are used) to identify and interpret defect indications. Post-Test Cleaning – The component is demagnetized and cleaned after inspection. Why It is Performed Magnetic Particle Testing is performed to ensure that fasteners and machined components are free from cracks or other surface-connected flaws that could compromise performance. Because many engineered fasteners are used in high-stress, safety-critical environments, even a small crack can propagate and lead to premature failure. MT is a fast, cost-effective, and highly sensitive method for detecting these flaws before components enter service. Detects surface and slightly subsurface cracks, seams, and laps Ensures quality and safety of ferromagnetic components Provides quick, reliable results to support efficient production and inspection cycles Application to Engineered Fasteners For engineered fasteners, surface and near-surface integrity is critical. Fasteners experience extreme loads, cyclic stresses, and environmental exposure in industries such as aerospace, oil & gas, and nuclear power. A small crack or seam undetected at the surface can become the origin of a failure under load. By applying Magnetic Particle Testing, TSP Manufacturing ensures: Fasteners are free of surface defects that threaten strength and reliability High-performance components meet industry and customer requirements Confidence in the long-term durability of fasteners used in safety-critical applications Standards & Compliance At TSP Manufacturing, Magnetic Particle Testing is carried out in strict accordance with ASTM, ASME, and customer-specific standards .

testing capabilities Cleanliness Test A Cleanliness Test is a quality inspection method used to determine the level of contaminants—such as oils, grease, machining residues, metal shavings, or foreign particles—present on a manufactured component. For engineered fasteners and precision-machined parts, even trace contamination can affect performance, assembly, or long-term reliability, making cleanliness verification a critical part of the quality process. How the Test is Performed Sample Preparation – The fastener or machined component is handled under controlled conditions to prevent outside contamination. Extraction of Contaminants – Solvents, ultrasonic agitation, or pressurized fluids are used to dislodge surface and embedded particles from the part. Collection & Filtration – Dislodged contaminants are collected and passed through a fine filter. Analysis – The particles and residues are measured by weight, size, or count using gravimetric, microscopic, or spectrographic methods. Evaluation Against Standards – Results are compared to customer or industry-defined cleanliness requirements. Why It is Performed Cleanliness Testing is performed to ensure that fasteners and machined components meet strict contamination-free requirements that protect assembly quality, performance, and durability. Prevents assembly issues such as galling, seizing, or torque misapplication Reduces risk of corrosion or premature wear caused by foreign particles Ensures compatibility with lubricants, coatings, and protective finishes Meets customer requirements for industries where contamination can cause system failure, such as aerospace, oil & gas, and defense Application to Engineered Fasteners Engineered fasteners often operate in demanding environments where any contamination can compromise safety and performance.

testing capabilities Grain Size Examination Grain Size Examination is a metallurgical test used to measure the average size of crystalline grains in a metal or alloy . Grain size plays a key role in determining mechanical properties such as strength, toughness, fatigue resistance, and corrosion performance. For engineered fasteners, controlling grain size is essential to ensuring they perform reliably under demanding conditions. How the Test is Performed Sample Preparation – A cross-section of the fastener or material is cut, mounted, and polished to a mirror finish. Etching – A chemical etchant is applied to reveal grain boundaries in the material. Microscopic Examination – The prepared sample is examined under an optical microscope. Measurement – Grain size is determined using comparison charts, line intercept methods, or digital image analysis in accordance with industry standards. Documentation – Results are recorded and compared against specification requirements. Why It is Performed Grain Size Examination is performed to confirm that the material’s microstructure supports the required mechanical properties .

MANUFACTURING PROCESSES Heat Treatment: Austenitizing Austenitizing is a critical stage in the heat treatment process, particularly for engineered fasteners and components made from steel and certain alloys. It is the process of heating the material to a temperature where its crystal structure transforms into austenite, a face-centered cubic (FCC) structure that allows for the redistribution of carbon and other alloying elements within the metal. This transformation is essential for subsequent heat treatment steps like quenching and tempering. The Austenitizing Process: 1. Preparation: The fastener or component is cleaned to remove any surface contaminants (oil, grease, or scale) that could interfere with the heat treatment process. 2. Heating to Austenitizing Temperature: The component is heated to a temperature range specific to the material: For carbon steels: Typically between 750°C and 950°C (1382°F to 1742°F). For alloy steels: The temperature varies depending on alloying elements but is generally higher. The goal is to transform the steel’s microstructure from ferrite (body-centered cubic, BCC) and pearlite into austenite (FCC). 3. Soaking: The component is held at the austenitizing temperature for a specific period to ensure uniform heating and complete transformation to austenite. The soaking time depends on the material’s size, composition, and thermal conductivity. 4. Redistribution of Carbon: During austenitizing, carbon and other alloying elements dissolve into the austenite, creating a uniform composition that sets the stage for subsequent heat treatment steps. 5. Cooling (Quenching): After austenitizing, the component is rapidly cooled (quenched) to lock in the desired microstructure, such as martensite, which provides high strength and hardness. Key Considerations for Austenitizing in Fastener Manufacturing: Material Selection: Not all materials can be austenitized; it is most effective for steels and specific alloys designed for heat treatment. Controlled Atmosphere: Using vacuum or inert gases (e.g., argon or nitrogen) prevents oxidation and decarburization during heating. Post-Treatment Inspection: Fasteners are inspected for hardness, microstructure, and dimensional stability after heat treatment to ensure quality. Benefits of Austenitizing for Fasteners: Uniform Microstructure: Austenitizing ensures that carbon and alloying elements are evenly distributed, providing consistent properties throughout the fastener. Improved Strength: Austenite transforms into martensite upon quenching, greatly enhancing the fastener’s hardness and strength. Customizable Properties: By controlling the austenitizing temperature and time, manufacturers can tailor the fastener’s properties to meet specific application requirements. Foundation for Toughness: Subsequent tempering processes build on the martensitic structure formed after austenitizing, balancing hardness and ductility. Applications in Engineered Fasteners: Austenitizing is a fundamental step in producing fasteners with enhanced mechanical properties, including: Bolts and Screws: High-strength bolts used in aerospace, automotive, and structural applications. Threaded Rods and Studs: Components requiring high tensile strength and wear resistance. Critical Fasteners: Custom fasteners used in extreme environments, such as oil & gas, nuclear power, and turbomachinery. Challenges in Austenitizing: Temperature Control: Precise control of temperature is crucial; overheating can lead to grain growth, weakening the fastener, while underheating may result in incomplete transformation. Decarburization: If not done in a controlled atmosphere (e.g., vacuum or inert gas), carbon can be lost from the surface, reducing the fastener’s strength. Quenching Cracks: Improper quenching after austenitizing can cause thermal stresses and cracking, especially in larger or more complex fasteners.
