The Fasteners Mart, situated in Mumbai, India, is a renowned supplier and exporter of high-quality industrial fasteners servicing global industry. We provide an extensive assortment of fasteners, such as Stainless Steel 310/310S Washers, popular for their superior strength and heat and corrosion resistance. Produced from Grade 310 and 310S austenitic stainless steel, these washers come in different shapes such as flat washers, spring washers, and lock washers. Their higher chromium and nickel content renders them well-suited for heavy-duty service in harsh temperature and corrosive conditions.
Stainless Steel 310/310S Washers consist of iron, chromium (24–26%), and nickel (19–22%), and Grade 310S contains a lower carbon level to improve weldability and decrease carbide precipitation. These washers provide a tensile strength of approximately 520 MPa, a yield strength of 205 MPa, and elongation of about 40%. With a specific gravity of 7.9 g/cm³ and a melting point of 1400–1455°C, they offer superior mechanical and physical properties such as resistance to thermal stress, oxidation, and scaling in elevated temperature conditions.
