ASTM A564 and heat treatment call out
ASTM A564 and heat treatment call out
(OP)
hello,
On the drawing of a stainless steel nut, we calls out the material 17-4 per ASTM A564.
Is this call out good enough or do we need to call out the heat treatment, for example precipitation?
Thanks.

A564 is a bar stock spec. but there is no reason items cannot be made from bar stock meeting the requirements of A564.
A564 items (bars, bolts, nuts etc.) can be purchased either annealed (no precipitation treatment which has been used to minimize galling when used with a 300 series stainless nut/bolt), or, for increased strength to any of the age hardening temperatures called out in the A564 Spec.
