High-temperature austenitic stainless steel pipes, known as 253MA pipes, are alloyed with roughly 21% chromium, 11% nickel, and minor but noteworthy additions of nitrogen and rare earth metals. These additions improve strength at high temperatures and resistance to oxidation. About 600 MPa of tensile strength and 310 MPa of yield strength are provided by 253MA pipes. At temperatures as high as 1150°C, the alloy exhibits remarkable performance. It is perfect for components exposed to thermal cycling and extended heat exposure because it combines good formability and weldability with exceptional creep resistance and structural stability.
