ASTM A376 Standard Specification.pdf
What is ASTM A376 material?
ASTM A376 is the standard specification for seamless austenitic steel pipe for high-temperature service. This standard covers seamless austenitic steel pipe suitable for high-temperature central station service, including five H grades and two nitrogen grades (such as 304N and 316N). The pipe can be hot- or cold-finished and requires appropriate finishing. It is typically supplied in the heat-treated condition and must pass various tests, such as tensile and hydrostatic tests, to ensure compliance with relevant requirements.
A376/A 376M Stainless Steel Seamless Pipe Chemical Composition
ASTM A376/A 376M covers seamless austenitic steel pipe intended for high-temperature service. The chemical composition of the specific grade within A376/A 376M, such as TP304, TP316, or TP321, will determine the exact percentages of elements like chromium, nickel, and others. Generally, austenitic stainless steels contain a significant amount of chromium and nickel.
A376/A 376M Stainless Steel Pipe Yield Strength
The yield strength of A376/A376M stainless steel pipe varies depending on the specific grade and temper. For example, ASTM A376 TP304 typically has a minimum yield strength of 205 MPa (30,000 psi), while ASTM A376 TP316 has a yield strength range of 30,000 to 50,000 psi in the annealed condition.
What is the difference between ASTM A312 and A376?
ASTM A312 and ASTM A376 are both specifications for seamless austenitic stainless steel pipes, but they differ in their intended applications and some specific requirements. ASTM A312 covers a wider range of applications, including general corrosive service and high-temperature service, while ASTM A376 is specifically for high-temperature service, particularly in central-station power plants.
What is the difference between ASTM A376 and A213?
ASTM A376 and A213 are both material specifications for steel tubes and pipes, but they differ in their intended applications and material types. ASTM A376 covers seamless austenitic steel pipe specifically for high-temperature central station service, while ASTM A213 covers seamless ferritic and austenitic alloy-steel tubes for boiler, superheater, and heat-exchanger applications
