Stainless Steel AISI 304 Fasteners

AISI 304 Equivalent Grades

AISI 4130 Bolts

Stainless Steel Alloy SS 304 fasteners are most widely used fasteners in corrosion resistant category. SS 304 fasteners are manufactured in wide range of bolts, screws, stud bolts, studs, threaded rods, nuts, washers & custom bolting parts. 304 stainless steel fasteners are exclusively produced in cold forged method under ASTM F593/F594 & BS EN ISO 3506-1/3506-2 specifications. Hot forged 304 stainless steel fasteners are produced under ASTM A182 F304, A193 Grade B8 & A194 Grade 8 specifications. SS 304 fasteners are well suited for its general corrosion resistance and aesthetic appearance.

304 Stainless Steel is an austenitic stainless steel and by far the most used stainless steel grade. Alternatively known by its grade equivalent AISI 304, DIN 1.4301 & UNS S30400. 304 is most versatile alloy with wide application spread. Due to its well known general corrosion properties and aesthetic appearance, SS 304 is a suitable alloy choice for manufacturing fasteners. It is also called as 18-8 Stainless Steel due to its chromium-nickel compositional ratio. It contains 18% Chromium to 8% Nickel approximately. AISI 304 has excellent forming and welding characteristics.
