Grade 316 is the standard molybdenum-bearing austenitic grade, particularly higher resistance to pitting and crevice corrosion in chloride environments. It is readily brake or roll formed,welded, soldered and cut by both thermal and mechanical methods.The austenitic structure gives excellent toughness, even down to cryogenic temperatures.Grade 316L, the low carbon version of 316, is highly resistant to sensitisation (grain boundary carbide precipitation) and so is extensively used in heavy gauge welded components (about 5mm and over). Grade 316H, with its higher carbon content has some application at elevated temperatures, as does stabilised grade 316Ti.
316L is actually a stainless steel material, which contains a certain amount of Mo element. The performance of this steel has exceeded that of 301 steel and 304 stainless steel. It has a very wide range of applications. Even in high-temperature environment, it will not be eroded and corroded by high temperature. It can also be used in the marine environment, and will not be polluted by some outer air, resulting in corrosion.
