Grade Overview
Introduction & Overview — 317L Stainless Steel Sheet
317L stainless steel sheet is a low-carbon, high-molybdenum stainless steel designed to provide greater resistance to corrosion. It has a higher molybdenum percentage than 316, greatly improving resistance to pitting and crevice corrosion in high abrasion environments. Its low carbon content ensures superior weldability without carbide precipitation.
