The 253MA (UNS S30815) is an austenitic stainless steel alloy crafted specifically for high-temperature uses. Its typical composition features 21% chromium, 11% nickel, 1.7% silicon, along with nitrogen and rare earth metals to boost oxidation resistance. This alloy boasts impressive mechanical strength and creep resistance at elevated temperatures. Notable mechanical properties include a tensile strength of about 600 MPa, yield strength of 310 MPa, and good elongation. These characteristics, paired with its outstanding oxidation resistance up to 1150°C, make 253MA sheets and plates ideal for extreme thermal environments.
