... common lubrication systems are MoS 2 , graphite, synthetics, and glass; however, MoS 2 is only useful at warm forging temperatures (up to 750 °F, or 400 °C). MoS 2 and graphite are solid lubricants. Because of their layered molecular structure, they demonstrate low frictional stresses. They are usually...
