ASTM A213 - Seamless steel pipe
Detailed introduction:
Use: Mainly used in boilers, superheaters and heat exchangers.
Steel type: Ferrite, austenite alloy steel.
Standard content: This standard specifies seamless steel pipes used for boilers, superheaters and heat exchangers, which can work for a long time in high temperature environment and have good anti-oxidation performance.
Main uses:
Heat exchangers, boilers, superheaters.
High temperature and high pressure systems.
Applicable to power plants, chemical plants and other industries.
ASTM A213 is used for high-temperature boilers and superheaters, and 304H and 316H are commonly used. The dimensions are similar to A312, and the wall thickness is mostly Schedule 5S–40S. The chemical composition of 304H/316H is similar to the corresponding austenitic steel, but the carbon content is increased to 0.04–0.10% to enhance the high-temperature strength. The physical properties are basically the same as A312: density 7.9g/cm³, Young's modulus 193GPa, thermal expansion coefficient 16×10⁻⁶/°C. The mechanical properties require that the tensile strength is ≥485MPa, the yield strength is ≥205MPa, and the elongation is ≥30% above 500°C.
