Stainless Steel 316L

Stainless Steel 316L (Supra 316L)

(UNS S31603) (EN 1.4404)

Supra 316L/4404 is our most widely used molybdenum-alloyed austenitic stainless steel. Supra 316L/4404 is a low-carbon stainless steel and is used in various process industries and other aggressive environments with higher than average corrosion resistance requirements. Due to its low carbon content, this product is also weldable in thicknesses of more than 5–6 mm/ 0.19–0.23 in without sensitivity to intergranular corrosion.

Supra 316L/4404 is an austenitic stainless steel that belongs to the standard CrNiMo stainless steels. Grade Supra 316L/4404 has low carbon content for improved resistance against intergranular corrosion after welding.

Due to their molybdenum content, the austenitic CrNiMo standard grades can be used in applications with increased demand for corrosion resistance. Their well-balanced material properties make them suitable for the fabrication of many products.
