316L Stainless Steel Flat Bar

The 316L stainless steel flat bar represents a premium grade in the austenitic stainless steel family. As a molybdenum-bearing grade, this stainless steel flat bar ranks as the second most popular choice after grade 304. What sets the 316L variant apart is its low carbon content, which prevents harmful precipitation during welding at temperatures between 800°F and 1500°F, making it ideal for heavy gauge welded components.
