Standards & threads
Finished boltASTM A1082/A1082MS32760 · special-purpose bolting
Specify the exact UNS and condition; include A962/A962M common requirements. Inch and metric designations are separate order choices, not mixed unit tables.
Do not treat S32750 and S32760 as one grade. Retain the S32760 identity and condition through material and finished-bolt records.
Raw material specificationASTM A276/A276M / ASTM A479/A479MUNS S32760
S32760 · stainless bar
Identify S32760, solution treatment and stock form. A182 F55 is a forging designation, not a finished hex-bolt performance class.
Dimensions · metricISO 4014 / ISO 4017Coarse pitch · partial-thread bolts / full-thread hex screws
Dimensions · inchASME B18.2.1Inch hex bolts / hex cap screws
Select the bolt or cap-screw pattern, head dimensions and thread length. Hex and heavy hex are different choices.
Threads · metricISO 261 / ISO 965-1Metric M · pitch plan and tolerance system

Technical help
Is F55 the finished-bolt specification for S32760?
A182 F55 is a forging designation. For the reviewed special-purpose bolting route, A1082/A1082M identifies S32760 and works with A962/A962M. Specify the finished condition, tests, dimensions and thread independently of a forging label.
Can a supplier substitute S32750 for S32760?
Retain S32760 unless a substitution is approved against the design requirements. The grades have separate identities. Compare the material condition and required corrosion and mechanical acceptance before agreeing to a change.
