Stainless Steel AISI 304H Fasteners

AISI 304H Equivalent Grades

AISI 4130 Bolts

SS 304H fasteners are manufactured in all types of bolts, screws, stud bolts, threaded rods, nuts, washers and other custom bolting parts. Stainless steel 304h fasteners are often produced in hot forged condition due to its high carbon content and relatively low forming properties.

Stainless steel alloy 304h is high carbon variant of traditional 304 grade for high temperature service with subsequent reduction in forming properties. SS 304H is alternatively know by its grade equivalent alloy AISI 304H, UNS S30409, DIN 1.4948 & SUS 304H.
