Condition CW – When Condition CW is specified, the austenitic alloys shall be annealed in accordance with Condition A, generally by the raw material manufacturer and thenc old worked to develop the specified properties. Condition AF – When Condition AF is specified, the ferritic alloys shall be annealed in accordance to same above condition A Ferritic Alloys after all cold working including heading and threading has been completed.
ASTM F – 09() Standard Specification for Stainless Steel Nuts
AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming. The finished fasteners shall meet the applicable mechanical 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 in accordance with Test Methods F A – Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed.
E When approved by the purchaser, alloy F may be furnished.
Condition CW – When Condition CW is specified, the ferritic alloys shall be annealed in accordance to above condition A for ferritic alloys, generally by the raw material manufacturer and then cold worked to develop the specified properties.

Historical Version s – view previous versions of standard. ASTM F covers seven groups of stainless steel alloys, including twelve austenitic, two ferritic, four martensitic and one precipitation hardening.
AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming G594 – Headed and rolled from annealed stock thus acquiring a degree of cold work.
SH – Machined from strain hardened stock or cold worked to develop the specific properties.
Seven groups of stainless steel alloys are covered, including ten austenitic, two ferritic, four martensitic, and one asttm hardening: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. D Yield strength is the stress at which an offset of 0. Link to Active This link will always route to the current Active version of the standard.
This specification covers the requirements for stainless steel nuts in specified size, inclusive, in nominal diameter in a number of alloys in common use and intended for service applications requiring general corrosion resistance.
