The Fasteners Mart, established in Mumbai, India, is a leading supplier and exporter of high-quality industrial fasteners to international markets. Among our products are Stainless Steel 253 MA Washers, which are produced from Grade 253 MA, an alloy that possesses outstanding high-temperature strength, oxidation resistance, and durability. These washers come in different shapes like flat, spring, and lock washers, ensuring consistent sealing and load distribution in harsh environments. With better performance, they can be used in harsh conditions, especially in high-temperature applications.
Stainless Steel 253 MA Washers contain iron, chromium (20–22%), nickel (10–12%), and cerium and yttrium in minor amounts. Their special composition gives them improved high-temperature oxidation resistance and mechanical strength. The tensile strength is about 600 MPa, and the yield strength is 300 MPa. The washers have a density of 7.9 g/cm³ and a melting point of about 1400°C. These washers offer excellent creep and oxidation resistance up to temperatures of 950°C and are suited to demanding applications.
