ASTM A213 T9 Alloy Steel Pipe For Power Generation Boilers
Specification
ASTM A213 T9 is a seamless alloy steel tube made of chromium-molybdenum that is designed for high-temperature and high-pressure applications like boilers, superheaters, and heat exchangers. It has excellent resistance to corrosion and oxidation at elevated temperatures, a minimum tensile strength of 415 MPa, and a yield strength of 205 MPa. The specific grade is defined by its 8.00-10.00% chromium and 0.90-1.10% molybdenum content.
