316Ti Stainless Steel Seamless Pipe is a titanium stabilised version of 316 molybdenum-bearing austenitic stainless steel . Các 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as 304. They also offer higher creep , stress-rupture and tensile strength at elevated temperature . 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 . This stabilisation is achieved by an intermediate temperature heat treatment , during which the titanium reacts with carbon to form titanium carbides . This significantly reduces susceptibility to sensitisation in service by limiting the formation of chromium carbides . Thus , the alloy can be used for extended periods at elevated temperatures without compromising its corrosion resistance . 316Của has equvilent corrosion resistance to sensitisation as the low carbon version 316L.more infor at stainless steel world
