Seamless Alloy Steel Pipe T9 Heat Exchanger Tube as per ASTM A213 Standard
ASTM A213 T9 is the part of ASTM A213 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, Heat-Exchanger Tubes. T9 Alloy Steel Seamless Tubes are Carbon Steel Tubes with subsequent addition of chromium, molybdenum and sometimes vanadium are known as chrome moly Tubes. ASME Specification alloy steel Tubes are used for high temperature service applications. Seamless Alloy Steel Tubes according to ASME SA 213 Grade T9 are reheated and furnished in full annlealed,isothermal annealed or normalized quenched and tempered condition.
