Stainless Steel Grade 316
-
316
Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 3164L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance.
-
313L
316L, the low carbon version of Stainless steel 316, is immune to grain boundary carbide precipitation (sensitization). This makes it suited to use in heavy gauge (over about 6mm) welded components.
-
313H, Ti
For elevated temperature applications the high carbon variant, 316H stainless steel and the stabilised grade 316Ti stainless steel should be employed.
The austenitic structure of Stainless steel 316 gives excellent toughness, even at cryogenic temperatures.
