Inquiry (采购产品): Nitrocarburizing Hi, my company has a need to case harden a steel ball-in-socket part. It is small (only a few inches long - ball dia. only about 1/2"), but it comes to us already yellow zinc plated. Is it possible to harden at least the ball/socket portion to improve wear resistance? Thanks in advance for your response! **** Hidden Message ***** Jim Frens 44 Miles Rd.
