Hot Forging Stainless Steel Bolts SS316 ASTM F593E Alloy Group For Building

ASTM F593G 1/4 to 5/8 F593H 3/4 to 1 - 1/2 Hex Bolts SS316 Stainless Steel Bolt

Product Description

A ANSI? 304 stainless steel hex Head bolt that is produced as ASTM F593 Group 1 must have additional processes performed that exceed the requirements of A193 grade B8. These bolts must be stamped with manufacturer’s identifier, “F593″, and the proper condition designation, and if the bolts are hot formed, they must also be carbide solution annealed. Additionally, F593 bolts must pass an intergranular corrosion test, which is not required when bolts are ordered as type 304 stainless steel or under the ASTM A193 grade B8 specification. F593 does not have the same 8UN series thread requirement above 1″ diameter as A193 grade B8, and is typically provided with Unified National Coarse threads. The F593 specification is also characterized by a maximum diameter of 1-1/2”.

F593 specification covers the chemical and mechanical requirements for stainless steel bolts, hex cap screws and studs in diameters ranging from 1/4" to 1-1/2" inclusive.Seven groups of stainless steel alloys are covered, including ten austenitic, two ferritic, four martensitic, and one precipitation hardening. These? fasteners are for general purpose usage and are available in seven alloy groups. Please contact us for more details by email
