Stainless Steel 316L Plate Prices

About 316L|Low carbon version of 316, purpose-built for welded fabrications in aggressive corrosive environments. The low carbon prevents chromium carbide precipitation during welding, maintaining corrosion resistance in the heat-affected zone. Slightly lower tensile and yield strength than standard 316, but the difference is minimal. Machines identically to 316 with the same challenges: gummy cutting, stringy chips, and high tool wear. Machinability around 40%. The material of choice when the spec says 316 and the fabrication involves welding, especially for chemical processing, offshore, and pharmaceutical applications. If you don't need to weld it, standard 316 (or dual-cert) works fine.

About Plate|Thick flat stock, generally 3/16" and up, used for machined base plates, fixture plates, wear surfaces, and structural fabrication. Heavier grades get milled, drilled, and tapped directly.
