The high-alloy austenitic stainless steel used to make Stainless Steel 253 MA Fasteners has additions of silicon, nitrogen, and rare earth elements to improve resistance to high-temperature oxidation, along with roughly 21% chromium and 11% nickel. With a tensile strength of about 600 MPa and a yield strength of about 310 MPa, these fasteners offer exceptional mechanical strength. Up to 1150°C, they provide exceptional resistance to thermal fatigue and scaling. 253 MA fasteners can be used in harsh industrial settings because of their good ductility, creep strength, and weldability, which allow them to retain their integrity in cyclic high-temperature environments.
