ASME SA213 TP304H Stainless Steel Tubes For High-Temperature And High-Pressure Superheaters
1. Description
H in ASME SA213 TP304H refers to high temperature, and high carbon content is the guarantee of high temperature strength. GB150 requires that when austenitic steel is used above 525 ℃, the carbon content shall not be less than 0.04%. Carbide is the strengthening phase, especially the high temperature strength is better than pure austenite.
ASME SA213 TP304H The usually used for Stainless steel boiler, superheater and heat exchanger.
