.... The bearing had not seized, and there was no evidence of heat discoloration in the galled areas. The inner cone, made of modified 4720 steel and carburized for wear resistance, rode on an AISI type 630 (17-4 PH) stainless steel spacer. Consequently, it was desirable to determine whether the galled spots...
