The mechanical properties for these two alloy groups are listed below. Hot-forged headed stainless steel bolts under the A specification require solution annealing after forging to restore full corrosion-resistant properties. 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 f5993 accordance with Test Methods F 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.

SH – Machined asrm strain hardened stock or cold worked to develop the specific properties. Your email address will not be published. Hex head, square head and hex socket cap screws. There are many differences between these two specifications.

ASTM A193 vs ASTM F593

B legend of conditions: If a scale-free bright finish is required, this must be specified in the purchase order. There are varying mechanical properties between the two specifications along with configuration differences for headed bolts and varying thread pitch requirements.

D Yield strength is the stress at which an offset of 0. There are also additional testing requirements for F which are not required under the A specification. A Where options are given, all the tests under an option shall be performed.

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.

ASTM F covers seven groups of stsinles steel alloys, including twelve austenitic, two ferritic, awtm martensitic and one precitipitain hardening. A Minimum values except where shown as maximum or as a range. Leave a Reply Cancel reply Asmt email address will not be published.

The fasteners under the ASTM A specification are designed to be used in high astmm or high pressure service, often in flanges and piping systems. A – Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed. Special fasteners have full size heads shall be tested as specified for stud bolts and other bolts. Leave this field empty.

The A specification is designed for use in high-temperature, high-pressure applications whereas F 5f93 used as more of a generic, all-purpose use fastener. F When approved by the purchaser, alloys or Se may be furnished. AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming.

The headed bolts in the F specification require a standard hex head pattern as sstm to heavy hex unless otherwise specified. 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 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.

Option A tests should be made whenever feasible. 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. F5993 Tensile stress areas are computed using the following formula: This specification covers the requirements 5f93 stainless steel bolts, hex cap screws, and stud bolts in imperial size 0.

Headed fasteners in this specification require a heavy hex pattern head unless otherwise specified. In order to understand these dissimilarities there are overviews of each specification below followed by a short summary of these variances.

There are multiple differences between these two specifications. 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. The F specification is more of a general purpose stainless steel specification used in all different applications.
