Stainless Steel 253MA Pipe Fittings consist of 20–23% Chromium, 4.5–6% Nickel, 0.8–1.2% Silicon, and 0.2–0.5% Molybdenum, with controlled levels of Manganese, Carbon, and Nitrogen added to enhance strength and stability. This special combination of alloys provides superior oxidation resistance, creep strength, and thermal stability at high temperatures. The fittings provide a minimum tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 35%. SS 253MA, with a melting point of 1375–1400°C, is suited for applications with extended exposure to severe heat and corrosive environments.
