Does ASTM A967 Practice D apply to age hardened 17-4 ph stainless steel?
Does ASTM A967 [affil link] Practice D-copper sulphate [on eBay or Amazon]Test apply to martensitic 17-4 ph stainless steel in the aged condition? I have passivated these parts per ASTM A380 [affil link] Code F. I'm assuming this spec does not apply because the parts are in the martensitic condition, but I'm not 100% sure, please advise.
Thanks,
