TP309H Stainless Steel Pipes & Tubes

Material Description UNS S30909 Chemical Composition, % C Mn P S Si Cr Ni .04-0.10 2.0 .045 .03 1.0 22.0-24.0 12.0-15.0 TP309H is an austenitic chromium-nickel steel with a low carbon content for high-temperature applications. Corrosion Resistance TP309H has a superior corrosion resistance to oxidation up to 1050°C, and the retention of a larger fraction of room temperature strength than common austenitic alloys. Good creep deformation resistance

Furnace equipments, tube hangers, chemical process industries such as hot concentrated acids, ammonia, sulfur dioxide, acetic and citric acid, and food processing industries.
