ASTM A213 Grade T5 Tube Overview
ASTM A213 Grade T5 is a seamless alloy steel tube designed for high-temperature service, commonly used in boilers, superheaters, and heat exchangers. Made from a 5Cr-0.5Mo alloy, it offers excellent strength, oxidation resistance, and thermal stability, making it ideal for applications in power plants, refineries, and petrochemical industries. It is part of the ASTM A213 standard, which covers seamless ferritic and austenitic steel tubes for pressure systems.
Why choose T5 grade?
· High strength at elevated temperatures
· Good oxidation resistance
· Suitable for long-term service in temperatures up to ~600°C (1110°F)
· Excellent for welding, bending, and forming operations
