Stainless Steel 317/317L washers are composed primarily of chromium (18-20%), nickel (11-14%), and molybdenum (3-4%), offering enhanced corrosion resistance compared to standard 304 stainless steel. They possess high strength, excellent pitting and crevice corrosion resistance, and superior performance in acidic environments. These washers are particularly beneficial in applications exposed to chlorides and other corrosive substances. Their robust durability and high-temperature resistance make them ideal for chemical processing, marine environments, and other demanding applications.

Stainless Steel 317/317L washers are used in environments requiring superior corrosion resistance, especially in the chemical, petrochemical, and marine industries. Their high molybdenum content enhances resistance to chloride pitting and crevice corrosion, making them ideal for seawater applications, acidic and alkaline environments, and high-temperature conditions. Common applications include securing bolts and nuts in flanges, pipelines, and equipment subjected to harsh conditions. They are also used in manufacturing and construction, where durability and resistance to corrosive substances are critical.
We ensure the highest quality for our Stainless Steel 317/317L Washers through rigorous testing, including Hardness, Chemical Analysis, Positive Material Identification (PMI), Flattening, Micro and Macro Tests, Pitting Resistance, Flaring, and Intergranular Corrosion (IGC) Tests. Each product is accompanied by detailed documentation, such as a commercial invoice, packaging list, Certificate of Origin, and a Guarantee Letter. Third Party Inspection Certificates are also provided to affirm our commitment to industry-leading standards.
