Machine shops with in-house heat treating in San Francisco

Heat treating — hardening, tempering, annealing, stress relief, case hardening — changes a metal's properties in the shop's own furnaces rather than at an outside vendor.

State the material, the hardness range or condition required and the spec (AMS 2759 etc.); ask what furnaces they run, whether they certify results and if NADCAP applies.
