Stainless Steel 317/317L Washers consist of chromium (18–20%), nickel (11–14%), and molybdenum (3–4%), which make them superior corrosion-resistant products, particularly in corrosive and chloride-bearing environments. Molybdenum addition provides resistance to pitting and crevice corrosion. The washers feature high yield and tensile strength, outstanding toughness, and high-temperature resistance. The low-carbon 317L version has better weldability and lower risk of carbide precipitation, guaranteeing durability over an extended period of time. Their mechanical strength makes them suitable for heavy-duty applications involving strength, stability, and high chemical resistance.
Stainless Steel 317/317L Washers are used extensively in industries where optimal corrosion resistance and strength are needed. They are typically used in the chemical and petrochemical industry for equipment, pipelines, and flanges that come in contact with aggressive acidic and alkaline conditions. In marine conditions, Stainless Steel 317/317L Washers can withstand seawater corrosion, and thus they are well suited for offshore platforms and shipbuilding. Their thermal stability at high temperatures makes them suitable in power stations and refinery plants, where equipment needs to handle intense heat. They are also utilized in construction and manufacturing, providing consistent fastening solutions for structural assemblies under corrosive materials and harsh operating conditions.
