Stainless Steel 253MA pipe fittings consist of about 21% chromium, 11% nickel, and 0.4% nitrogen content that strongly improves creep strength and oxidation resistance. Pipe fittings have tensile strength of about 600 MPa and yield strength of about 300 MPa. The composition of the alloy is excellent in resisting scaling, sulfidation, and thermal fatigue, which gives it suitable for continuous operation at temperatures up to 1100°C.
