Hot-forged headed stainless steel bolts under the A specification require solution annealing after forging to restore full corrosion-resistant properties. If a scale-free bright finish is required, this must be specified in the purchase order.

ASTM A vs ASTM F – Portland Bolt

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. E When approved by the purchaser, alloy F may be furnished. Leave a Reply Cancel reply Your email address will not be published. AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming.

Your email address will not be published. There are many differences between these two specifications. SH – Machined from strain hardened stock or cold worked to develop the specific properties. This test adds to both the cost and lead time to produce this grade of stainless headed bolt. D When approved by the purchaser, alloysSe, or XM1 may be furnished. B Tests that are not mandatory C Special fasteners are those fasteners with special configurations including drilled heads, reduced body, etc.

A – Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed. ASTM F covers seven groups of stsinles steel alloys, including twelve f5593, two ferritic, four martensitic and one precitipitain hardening. A Where options are given, all the tests under an option shall be performed. The mechanical properties for these two alloy groups are listed below. F When approved by the purchaser, alloys or Se may be furnished.

Headed fasteners in this specification require a heavy hex pattern head unless otherwise specified.

There are also additional testing requirements for F which are not required under the A specification. This specification covers the requirements for stainless steel bolts, hex cap screws, and stud bolts in imperial size 0. 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.

D Yield strength is the stress at which an offset of 0. A Tensile stress areas are computed using the following formula: 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 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 CW – Headed and rolled from annealed stock thus acquiring a degree of cold work.

What are the differences between F and A stainless steel headed bolts? In order to understand these dissimilarities there are overviews of each specification below followed by zstm short asstm of these variances. The fasteners under the ASTM Asfm specification are designed to be used in high temperature or high pressure service, often in flanges and piping systems.

ASTM F593 Specification

A Minimum values except where shown as maximum or as a range. 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.

Option A tests should be made whenever feasible. There are multiple differences between these two specifications. Do you have a job that requires A or F stainless steel fasteners?

ASTM A193 vs ASTM F593

Leave this field empty. The headed bolts in the F specification require a standard hex head pattern as opposed to heavy hex unless otherwise specified. The F f5993 is more of a general purpose stainless steel specification used in all different applications. There are varying r593 properties between the two specifications along with configuration differences for headed bolts and varying thread pitch requirements.

B legend of conditions: 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. 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.
