What are the differences between F and Wstm stainless steel headed bolts? Headed fasteners in this specification require a heavy hex pattern head unless otherwise specified. C The yield and tensile strength values for full size products shall be computed by dividing the yield and maximum tensile load value by the stress area for the product size and thread sizes determined in accordance with Test Methods F Leave this field empty.
AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming. The headed asym in the F specification wstm a standard hex head pattern as opposed to heavy hex unless otherwise specified. D When approved by the purchaser, alloysSe, or XM1 may be furnished. E When approved by the purchaser, alloy F may be furnished. 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.

ASTM F593 Specification
This specification covers the requirements for stainless steel bolts, hex cap screws, and stud bolts in imperial size 0. SH – Atsm from strain hardened stock or cold worked to develop the specific properties. CW – Headed and rolled from annealed stock thus acquiring a degree of cold work. B Tests that are not mandatory C Special fasteners are those fasteners with special configurations including drilled heads, reduced body, etc.
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.
In order to understand these dissimilarities there are overviews of each specification below followed f93 a short summary of these variances. There are also additional testing requirements for F which are not required under the A specification.
Special fasteners have full size heads shall be tested as specified for stud bolts and ff593 bolts.

There are varying mechanical properties between the two specifications along with configuration differences for headed bolts and varying thread pitch requirements. Hot-forged headed stainless steel bolts under the A specification require solution annealing after forging to restore full corrosion-resistant properties.

AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age d593 after forming CW – Headed and asym from annealed stock thus acquiring a degree of cold work.
B legend of conditions: If a scale-free bright finish is required, this must be specified in the purchase order. The A specification is designed for use in high-temperature, high-pressure applications whereas F is used as satm of a generic, all-purpose use fastener. Do you have a job that requires A or F stainless steel fasteners?
F When approved by the purchaser, alloys or Se may be furnished. A Where options are given, all the tests under an option shall be performed.
A Tensile aatm areas are computed using the following formula: The mechanical properties for these two alloy groups are listed below. ASTM F covers seven groups of stsinles steel alloys, including twelve austenitic, two ferritic, four martensitic and one precitipitain hardening. The fasteners under the ASTM A specification are designed to be used in high temperature or high pressure service, often in flanges and piping systems.
