1. What is ASTM A960?
A: ASTM A960 is a standard developed by the American Society for Testing and Materials (ASTM). Its full title is "Standard Specification for Common Requirements for Wrought Steel Piping Fittings." It specifies common manufacturing, testing, and acceptance requirements for carbon steel, alloy steel, and stainless steel pipe fittings (such as elbows, tees, flanges, etc.).
2. What materials does this standard apply to?
A: It primarily applies to forged or machined carbon steel (such as A105), alloy steel (such as A182 F11/F22), and stainless steel (such as A182 F304/F316) pipe fittings, typically used in high-pressure, high-temperature, or corrosive environments.
3. How does ASTM A960 relate to other piping standards (such as ASME B16.9)?
A: Standards like ASME B16.9 focus on fitting dimensions and tolerances, while ASTM A960 supplements these with general requirements for materials, manufacturing processes, and testing. The two are often used together to ensure interchangeability and performance consistency of components.
4. What are the key test items specified in the standard?
A: These include, but are not limited to:
• Chemical composition analysis (material conformity);
• Mechanical property testing (e.g., tensile strength, hardness);
• Nondestructive testing (e.g., radiographic testing, ultrasonic testing);
• Pressure testing (e.g., hydrostatic pressure testing).
5. What is the latest version of ASTM A960?
A: As of 2025, the latest version is ASTM A960-23.
