Stainless Steel Alloy 317L

Description

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
