The Fasteners Mart in Mumbai, India, is a prominent exporter and supplier of premium fasteners to industries all over the world. Our Stainless Steel 253 MA Fasteners are produced from Grade 253 MA, a high-performance austenitic stainless steel. It is renowned for its superior high-temperature resistance, oxidation, and corrosion resistance and is used widely in severe environments. These fasteners are available in different shapes, including bolts, nuts, washers, and studs, providing reliability and durability for use in applications demanding high strength and heat and corrosion resistance.
Stainless Steel 253 MA Fasteners consist of iron, chromium (20–22%), nickel (10–12%), and traces of rare elements like cerium and yttrium, which increase their high-temperature resistance. The fasteners have a tensile strength of around 600 MPa, with a yield strength of 300 MPa. The density of the material is 7.9 g/cm³ and the melting point is around 1400°C. With superior oxidation and creep properties at high temperature, they have good performance in severe environments to 950°C.
