SMO 254 (UNS S31254) is a high-alloy austenitic stainless steel known for its outstanding corrosion resistance. Its unique composition features about 20% chromium, 18% nickel, 6% molybdenum, along with some nitrogen and copper. This blend gives it remarkable resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. On the mechanical side, SMO 254 boasts a tensile strength of around 650 MPa, a yield strength of 300 MPa, and impressive elongation properties. It maintains excellent toughness and strength, even in the harshest conditions. These hex bars and rods are perfect for high-pressure and high-temperature applications in aggressive chemical and marine settings.
