The Mumbai, India-based Fasteners Mart is a premier distributor of quality fasteners with expertise in a variety of products for construction, automotive, marine, and aerospace industries. The company offers a wide variety of fasteners, including Stainless Steel 317/317L washers. The washers are produced from austenitic stainless steel alloys, grades 317 and 317L, that possess high resistance to corrosion, heat, and pressure. The washers are available in different shapes such as beveled and flat, with shapes that suit their application in rough and corrosive conditions where increased durability is needed.
Stainless Steel 317/317L washers are composed of 18-20% chromium, 3-4% molybdenum, and 10-12% nickel, with Grade 317 containing higher molybdenum for enhanced corrosion resistance. Grade 317L has lower carbon content, improving weldability. These washers exhibit tensile strength ranging from 500 MPa to 700 MPa and yield strength of approximately 250 MPa. They offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, even in acidic and chloride-rich environments. Physically, these washers maintain high strength at elevated temperatures and provide long-lasting performance.
