AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming. What are the differences between F and A stainless steel headed bolts? Special fasteners have full size heads shall be tested as specified for stud bolts and other bolts. C The yield and tensile strength values for full size products asym be computed by dividing the yield and maximum tensile load value by the stress area for the product size and thread ast determined in accordance with Test Methods F The mechanical properties for these two alloy groups are listed below.

Hot-forged headed stainless steel bolts under the F specification are manufactured to either Condition A asym Condition CW which both require solution annealing after forging to restore full corrosion-resistant properties.

This specification covers the requirements for stainless steel bolts, hex cap screws, and stud bolts in imperial size 0. F When approved by the purchaser, alloys or Se may be furnished. asttm

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. Hex head, square head and hex socket cap screws. D When approved by the purchaser, alloysSe, or XM1 may be furnished. 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.

Option A tests should be made whenever feasible. AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming CW – Headed and rolled from g593 stock thus acquiring a degree of cold work.

Leave this field empty. B Tests that are not mandatory C Special fasteners are those fasteners with special configurations including drilled f5593, reduced body, etc. This test adds to both the cost and lead time to produce this grade of stainless headed bolt. CW – Headed and rolled from annealed stock thus acquiring a degree of cold work.

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. If a scale-free bright finish is xstm, this must be specified in the purchase order.

The headed bolts in the F specification require a standard hex head pattern as opposed to heavy hex unless otherwise specified. D Yield strength is the stress at which an offset of 0. In order to understand these dissimilarities there are overviews of each specification below followed by a short summary of these variances.

There are also additional testing requirements for F which are not required under the A specification. A Tensile stress areas are computed using the following formula: The fasteners under the ASTM A specification are designed to be used in high temperature or high pressure service, often in zstm and piping systems.

SH – Machined from strain hardened stock or cold worked to develop the specific properties. B legend of conditions: There are varying mechanical properties between the two specifications along with configuration differences for headed bolts and varying thread 5f93 requirements.

ASTM A193 vs ASTM F593

There are many differences between these two specifications. Your email address will not be published.

Do you have a job that requires A or F stainless steel fasteners? Hot-forged headed stainless steel bolts under the A specification require solution annealing after forging to restore full corrosion-resistant properties. A Where options are given, all asfm tests under an option shall be performed.

Leave a Reply Cancel reply Your email address will not be published. There are multiple differences between these two specifications. E When approved by the purchaser, alloy F may be furnished. Headed fasteners in this specification require a heavy hex pattern head unless otherwise specified.

Asfm – Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed.

A Minimum values except where shown as maximum or as a range. ASTM F covers seven groups of stsinles steel alloys, including twelve austenitic, two ferritic, four martensitic and one precitipitain hardening. The F specification is more of a general purpose stainless steel specification used in all different applications.
