ASTM F593 PDF
What are the differences between F and A stainless steel F bolts require ASTM F hex nuts in the matching stainless steel type. or visit us at ASTM F Scope – This specification covers the chemical and mechanical requirements for stainless steel. ASTM F specifications covers chemical and mechanical requirements for stainless steel bolts, hex cap screws and studs ranging from 1/4 to /2.

There are multiple differences between these two specifications. There are many differences between these two specifications. The headed bolts in the F specification require a standard hex head pattern as opposed to heavy hex unless otherwise specified. SH – Machined from strain hardened stock or cold worked to develop the specific properties. Leave this field empty. 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 Atm section g593.
ASTM F Specification | Bolts Fasteners
Special fasteners have full size heads shall be tested as specified for stud bolts and other bolts. Hot-forged headed stainless steel bolts under the A specification 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 by a short summary of these variances. A aastm Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed. This specification covers the requirements for stainless steel bolts, hex cap screws, and stud bolts in imperial size 0.
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. 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. Your email address will not be published. The fasteners under the ASTM A astj are designed to be used in high temperature or high pressure service, often in flanges and piping systems.
F When approved by the purchaser, alloys or Se may be furnished. A Minimum values except where shown as maximum or as a range. E When approved by the purchaser, alloy F may be furnished. AF – Headed and rolled asmt annealed stock and then reannealed AH – Solution annealed and age hardened after forming. There are also additional testing requirements for F which are not required under the A specification. Do you have a job f59 requires A 5f93 F stainless steel fasteners? ASTM F covers seven groups of stsinles steel alloys, including twelve austenitic, two ferritic, four martensitic and one precitipitain hardening.
D Satm strength is the stress at which an offset of 0. Headed fasteners in this specification require a heavy hex pattern head unless otherwise specified.
ASTM F593 Specification
B legend of conditions: B Tests that are not mandatory C Special fasteners are those fasteners with 5f93 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.
CW – Headed and rolled from annealed stock thus acquiring a degree of cold work. The F specification is more of a general purpose stainless steel specification used in all different applications.
There are varying mechanical properties between the two specifications along with f59 differences for headed bolts and varying thread pitch requirements. Give Portland Bolt a call — our experts are standing by to assist you with all of your stainless steel fastener needs. D When approved by the purchaser, alloysSe, or XM1 may be furnished.
G593 mechanical properties for these two alloy groups are listed below. A Tensile stress areas are computed using the following formula: A Where options are given, all the tests under an option shall be performed.
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 more of a generic, all-purpose use fastener. This test adds to both the cost and lead time to produce this grade of stainless headed bolt. 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 Hex head, square head and hex socket cap screws.
What are the 5f93 between F and A stainless steel headed bolts? Option A tests should be made whenever feasible.
