304 Stainless Steel Introduction
Type 304H, with higher carbon content, is normally specified where good mechanical properties at elevated temperatures are required. The higher carbon content may lead to sensitization with a concomitant loss of corrosion resistance in a corrosive environment. Welding procedures should be selected with care.
