Name: China ASTM A213 T22 Alloy Steel pipe Manufacturers Suppliers Factory - Customized Service - Gnee Steel
Brand: GNEE
SKU: 239903315

ASTM A213 T22 heat exchanger tube is a 2.25Cr-1Mo chromium-molybdenum high temperature ferritic steel with excellent high temperature performance and mechanical properties.
The chemical composition of ASTM A213 grade T22 alloy steel seamless tube has 1.90-2.60 chromium and 0.87-1.13 molybdenum added. The minimum tensile strength under load is 415 MPa and the minimum yield strength of ASTM A213 grade T22 tube is 205 MPa. In high temperature environment, ASTM A213 T22 seamless heat exchanger tube is able to maintain high strength and has good creep resistance and lasting strength.
