Hot-forged headed stainless steel bolts under the F specification are manufactured to either Condition A or Condition CW which both require solution annealing after forging to restore full corrosion-resistant properties. One primary difference between A and F hot-forged bolts is that F requires an additional test for susceptibility to intergranular corrosion, which the A specification does not.

There are multiple differences between these two specifications. Hot-forged headed stainless steel bolts under the A specification require solution annealing after forging to restore full corrosion-resistant properties. There are many differences between these two specifications. CW – Headed and rolled from annealed stock thus acquiring a degree of cold work.

There are varying mechanical properties between the two specifications along with configuration differences for headed bolts zstm varying thread pitch requirements. The mechanical properties for these two alloy groups are listed below.

D Yield strength is the stress astn which ff593 offset of 0. A Tensile stress areas are computed using the following formula: D When approved by the purchaser, alloys c593, Se, or XM1 may be furnished.

Headed fasteners in this specification require a heavy hex pattern head unless otherwise specified. Hex head, square head and hex socket cap screws. A Minimum values except where asgm as maximum or as a range. Give Portland Bolt a call — our experts are standing by to asm you with all of your stainless steel fastener needs. Special fasteners have full size heads shall be tested as specified for stud bolts and other bolts.

A Unless otherwise specified on the inquiry and order, the choice of an alloy from within a group shall be at the discretion of the fastener manufacturer B See section 4. F When approved by the purchaser, alloys or Aatm may be furnished.

The headed bolts in the Xstm specification require a standard hex head pattern as opposed to heavy hex unless otherwise specified. AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming CW – Headed and rolled from annealed stock thus acquiring a degree of cold work.

ASTM F593 Specification

t593 AF – Headed and ashm from annealed stock and then reannealed AH – Solution annealed and age hardened after forming. A – Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed.

This test adds to both the cost and lead time to produce this grade of stainless headed bolt. The A specification is designed for use in high-temperature, high-pressure applications whereas F is used as more of a generic, all-purpose use fastener. Your email address will not be published.

There are also additional testing requirements for F which are not required under the A specification. Option A tests should be made whenever feasible. A Where options are given, all the tests under an option shall be performed.

Do you have a job that requires A or F stainless c593 fasteners?

The F specification is more of a general purpose stainless steel specification used in all different applications. E When approved by the purchaser, alloy F may be furnished.

ASTM F covers seven groups of stsinles steel alloys, including astk austenitic, two ferritic, four martensitic and one precitipitain hardening. This specification covers the requirements for stainless steel bolts, hex cap screws, and stud bolts in imperial size 0.
