SMO 254 Pipe Fittings are produced from a high-alloy austenitic stainless steel with very high molybdenum (approximately 6%), chromium, and nitrogen content, providing superior resistance to crevice corrosion, pitting, and stress corrosion cracking. The alloy offers mechanical strength with tensile strength of about 650 MPa and yield strength of about 300 MPa. SMO 254 has fine ductility and impact toughness even at low temperatures. The matching of corrosion resistance and high strength makes it suitable for harsh service conditions, particularly in chloride-containing and acidic environments.
