ASTM A269 TP316Ti UNS S31635 Seamless Tube Chemical Containers
TP316Ti （UNS S31635） is a titanium stable version of 316 molybdenum austenitic stainless steel. 316 alloy is more resistant to general and pitting/gap corrosion than traditional chrome-nickel austenitic stainless steel (e.g. 304). They also provide higher creep， stress fracture and tensile strength at high temperatures.
ASTM A269 TP316Ti Stainless Steel Tubes
Stainless steel is often called corrosion-resistant steel — it doesn't stain， corrode， or rust as easily as normal carbon steel. However， it is misleading to say that it is corrosion resistant. It differs significantly from standard carbon steel due to its chromium content， which limits surface corrosion， and carbon steel rusts when exposed to any moisture in the air and atmosphere. Stainless steel is often a popular solution due to its oxidation resistance properties.
