The composition of our Stainless Steel 253 MA Stud Bolts primarily includes iron, along with chromium (20–22%), nickel (10–12%), silicon (~1.6%), and nitrogen, all of which enhance high-temperature strength and oxidation resistance. This unique alloy performs exceptionally well at temperatures reaching up to 1100°C. With a tensile strength of about 600 MPa and a yield strength of around 310 MPa, these bolts are built to resist thermal fatigue, scaling, and high-temperature corrosion, even in challenging oxidizing and carburizing environments. This makes them perfect for structural applications where thermal stability is a must.
