Mumbai, India-based Fasteners Mart is a globally acclaimed fasteners supplier and exporter of top-class fasteners serving different industries all over the world. Our Stainless Steel 253 MA Bolts are fabricated with Grade 253 MA, an advanced performance alloy possessing excellent heat resistance and oxidation resistance. Available in multiple forms such as hexagonal, square, and others as per order, these bolts provide additional strength and durability in harsh conditions of application. The composition of the material provides these bolts with superior performance in conditions where corrosion resistance and high temperature resistance are paramount.
Stainless Steel 253 MA Bolts consist of iron, chromium (20–22%), nickel (10–12%), and trace amounts of rare elements such as cerium and yttrium, which add to the alloy’s high-temperature stability. The bolts have a tensile strength of 600 MPa, with yield strength of 300 MPa, and thus are ideal for heavy-duty uses. The density is 7.9 g/cm³ and the melting point is approximately 1400°C. The alloy provides strong resistance to oxidation, creep, and scaling under high-temperature conditions, perfect for harsh conditions.
