Stainless Steel 317/317L Washers consist of chromium (18–20%), nickel (11–14%), and molybdenum (3–4%), which contribute extensively to increased corrosion resistance than common grades such as 304. With their high molybdenum content, they provide excellent resistance to pitting, crevice corrosion, and acidic conditions. They exhibit superior mechanical strength, toughness, and resilience even at elevated temperatures and corrosive conditions. The 317L grade, with its reduced carbon content, offers better weldability and reduces carbide precipitation on welding. Coupled together, these characteristics make Stainless Steel 317/317L Washers highly dependable for severe industrial fastening use.
Stainless Steel 317/317L Washers are extensively applied in industries demanding high corrosion resistance and durability. In the chemical and petrochemical industries, they fasten flanges, pipelines, and equipment coming in contact with aggressive acids and chlorides. The marine sector appreciates their seawater corrosion resistance, while power plants and refineries use them for high-temperature applications. They also find application in construction and manufacturing industries where long-term reliability is paramount.
