ASTM A213 SS 347 Tube is a stabilized austenitic stainless steel alloy containing alloying elements such as niobium and tantalum. Chromium and nickel components provide good resistance to oxidation and carburization. Creep stress and rupture properties are higher than TP304. Suitable for high temperature service 800 to 1500°F (427 to 816°C). It is resistant to common corrosive media such as sulfuric acid, hydrochloric acid and alkaline solutions.
