7、t-treating operations, including tempering or stress relief, shall be completed prior to plating. Steel parts containing 0.35% carbon or more at the surface, or heat treated to Rockwell C 30 or higher, or highly stressed cold-worked parts, shall be heated within 1 h maximum after plating to a temper
8、ature of 205 C for 4 h at heat. Higher temperature and/or longer times may be used if necessary to avoid any detrimental effects of hydrogen embrittlement. Hardened parts which have been tempered at less than 205 C shall be heated within 1 h maximum after plating to a temperature of 150 C for 8 h at heat, or longer if necessary. 3.5 DETERMINATION OF COATING THICKNESS The amount of copper deposit on the exposed surface shall be determined by optical measurements on a polished section or by an approved mechanical device such as magnegage.
