Austenitic steel ASME SA213 · TP317

Short Description:

The high-molybdenum chromium-nickel austenitic stainless steel is mainly used in chemical processing, petrochemical plants, flue gas desulfurization systems, and paper manufacturing. Specially alloyed with elevated molybdenum levels to provide superior resistance to pitting, crevice corrosion, and chemical attack by chlorides compared to standard 316 grades, this grade maintains outstanding creep and tensile strength at elevated temperatures. Furthermore, this grade is suitable for TIG, MAG and manual arc welding procedures.
