Stainless Steel 440B Washers are made from high-carbon martensitic stainless steel of the 440B grade. Stainless Steel 440B Washers are available in a range of shapes such as flat, square, and custom shapes, used for high-load and high-wear applications. The 440B material has high hardness, wear resistance, and moderate corrosion resistance. Its composition enables it to be heat-treated to obtain greater strength, and hence it is best suited for application in precision fastening where toughness and close tolerance are important. These washers can be used for both structural and mechanical applications in harsh environments.

Stainless Steel 440B Washers generally consist of Carbon (0.75%), Chromium (16–18%), Manganese (1%), Silicon (1%), and traces of Molybdenum. Following heat treatment, they exhibit high tensile strength (as high as 760 MPa), good hardness (as high as 58 HRC), and good wear resistance. They have a melting point of between 1480–1530°C and a density of 7.75 g/cm³. They show dimensional stability and performance under mechanical load. Less corrosion-resistant compared to austenitic grades, they are nevertheless adequate in less aggressive environments and are suitable for parts that demand high hardness and durability.
The Fasteners Mart provides quick and guaranteed delivery of Stainless Steel 440B Washers to both local and international clients. Washers are packaged safely in rust-proof and moisture-proof materials like bubble wraps, boxes, or wooden crates to avoid damage or rust.
