Known as the most versatile and the Stainless Steel 304 Fasteners is most widely used of all conventional stainless steel grades. The amalgamation of its chemical composition along with mechanical properties, good weldability as well as good corrosion resistance is what attracts our clients to stainless steel grade 304. This austenitic SS 304 threaded rod offers the best all-round performance as compared to alloy steel as well as carbon steel, that too at relatively low cost. Moreover, the Stainless Steel 304 nuts are resistant to oxidation corrosion.
Stainless Steel 304 Fasteners
Grade 304 also has excellent low temperature properties and can be used in applications involving cryogenic temperatures. Since stainless steel 304 is an austenitic alloy that responds well to hardening when the fasteners have been cold worked, the metal not only becomes much stronger, but the surface of the fasteners can be smoothened as well. In most environments and applications, the UNS S30400 bolts produced from this alloy tends to exhibit superior properties to that of ferritic stainless steels grades.
Essentially a non-magnetic stainless steel grade however, the SS 304 studs becomes slightly magnetic when cold worked. Since the alloy has a low carbon content, it would imply a reduced occurrence of carbide precipitation in the heat-affected area during welding operations. Therefore the SS 304 hex bolt has reduced susceptibility to intergranular corrosion. Although the alloy can be welded using traditional procedures, stainless steel grade 304 must compulsorily be annealed in order to restore the corrosion resistance properties that are lost by sensitization. Generally, sensitization to intergranular corrosion occurs in instances where chromium carbides precipitate in the grain boundaries of the welded heat-affected area.
