Description
ASTM A193 B8MLCuN SMO 254 Hex Bolts
ASTM A193 B8MLCuN SMO 254 Hex Bolts, are engineered for demanding applications where exceptional corrosion resistance, strength and long-term reliability are required. 254 SMO, also known as UNS S31254, is a 6% molybdenum super-austenitic stainless steel. These hot forged hex bolts are suitable for aggressive chloride, seawater and chemical environments.
ASTM A193 B8MLCuN SMO 254 Hex Bolts are manufactured from UNS S31254 material and can be supplied to ASTM A193 Grade B8MLCuN requirements. The material offers excellent resistance to pitting, crevice corrosion and stress corrosion cracking compared with conventional stainless steel grades such as 316L.
