Stainless Steels - Stainless 316 Properties, Fabrication and Applications

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.

 

316 Stainless Steel

Stainless steel 316 contains an addition of molybdenum that gives it improved corrosion resistance. This is particularly apparent for pitting and crevice corrosion in chloride environments.

 

316L Stainless Steel

316L, the low carbon version of Stainless steel 316, is immune to grain boundary carbide precipitation (sensitisation). This makes it suited to use in heavy gauge (over about 6mm) welded components.

 

316Ti and 316H Stainless Steels

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.

 

ASTM A240/A240M

Property data given in this document is typical for bar and section products covered by EN 10088-3:2005. ASTM, EN or other standards may cover all products sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

 

Stainless steel grade 316Ti contains a small amount of titanium. Titanium content is typically only around 0.5%. The titanium atoms stabilise the structure of the 316 at temperatures over 800°C. This prevents carbide precipitation at the grain boundaries and protects the metal from corrosion. The main advantage of 316Ti is that it can be held at higher temperatures for a longer period without sensitisation (precipitation) occurring. 316Ti retains physical and mechanical properties similar to standard grades of 316.
