Sumit Impex is a reputable manufacturer and supplier of Stainless Steel 317/317L Fasteners. These fasteners are specially designed to meet the requisite quality and durability standards. This type of austenitic stainless steel contains 18% chromium, 13% nickel, and 3% molybdenum. Such an outstanding corrosion resistance makes them suitable for use in very aggressive environments, especially where chloride stress corrosion, pitting, and crevice corrosion are anticipated. The lower carbon content in the Stainless Steel 317L Fasteners has also made it more readily weldable; thus, these are largely utilized in high-temperature applications.
Sumit Impex is a Supplier of Stainless Steel 317 Fasteners, Biggest Stockist of 317/317L SS Fasteners as per Standards in Mumbai, India.
