ASTM A312 UNS31635 TP316TI Tubo senza saldatura in acciaio inossidabile

316Ti Stainless Steel Seamless Pipe is a titanium stabilised version of 316 molybdenum-bearing austenitic stainless steel. High carbon Alloy 316 stainless steel can be susceptible to sensitisation, the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500°F (425 to 815°C) which can result in intergranular corrosion. Resistance to sensitisation is achieved in Alloy 316Ti with titanium additions to stabilise the structure against chromium carbide precipitation, which is the source of sensitisation. 316Ti has equvilent corrosion resistance to sensitisation as the low carbon version 316L.more infor at stainless steel world
