Alloy 254SMO Fasteners, UNS S31254

AISI 4130 Bolts

Alloy 254SMO fasteners are manufactured in all forms of bolts, screws, stud bolts, studs, threaded rods, nuts, washers and other custom as per drawing fastening parts, in metric and imperial sizes. Alloy 254smo fasteners are commonly produced in forging specification ASTM A182 F44, widely used for bolting application in food and beverage, chemical processing, desalination plants, petroleum, paper & pulp industries. Most commonly used fasteners in 254smo are stud bolts with heavy hex nuts, manufactured to ASTM A182 F44 grade specification. Alloy 254 fasteners are often produced in grade equivalent UNS S31254 & DIN EN 1.4547. ASTM A193 also covers grade specification B8MLCuN/B8MLCuNA for S31254 bolts, screws, stud bolts and A194 grade 8MLCuN/8MLCuNA for nuts.
