Type 317L is a low carbon austenitic stainless steel version of Type 317 that offers improved corrosion resistance over Type 304/304L. Some of the other major benefits of Type 317L include:
Better general and localized corrosion resistance compared to 316/316L stainless steel
Good formability and weldability
Increased resistance to chemical attack from acids
Lower carbon content leads to resistance to sensitization when welded
Non-magnetic
Like all stainless steels, Type 317L has a unique chemical composition that includes the following:
Fe Balance
Cr 18-20%
Ni 11-15%
Mn 2%
Si 0.75%
C 0.03%
N 0.1%
S 0.03%
P 0.045%
Because of Type 317L benefits and chemical composition, it is used extensively in a variety of industries for many applications including:
Paper and pulp equipment
Chemical and petrochemical processing
Food processing
Power generation including fossil fuels and nuclear
Flue gas desulfurization systems
The Alloy 317L, we supply meets or exceeds many of the leading international standards including those from ASTM, ASME, UNS, DIN, and EN.
