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.
Seven groups of stainless steel alloys are covered, including ten austenitic, two ferritic, four martensitic, and one precipitation hardening: 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.
Chemical tests; mechanical tests; and corrosion resistance shall be performed to conform with the specified requirements. E When approved by the purchaser, alloy F may be furnished.
F When approved by the purchaser, alloys or Se may be furnished. Unless otherwise specified, all bolts, hex cap screws, and studs used with these nuts shall conform to the requirements of Specification F and shall be of the same alloy group. 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 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.
SH – Machined from strain hardened stock or cold worked to develop the specific properties. 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. Condition AF – When Condition AF is specified, the austenitic alloys shall be annealed in accordance to Condition A after all cold working including heading and threading has been completed. 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.
