Heat-resistant bearing material used for bearing ring comprises austenitic iron matrix alloy with sulfur content sufficient for producing solid lubricating action on its bearing surface

摘要

A heat resistant bearing material comprises an austenitic iron matrix alloy with a sulfur content sufficient for producing a solid lubricating action on its bearing surfaces and 1-6 wt.% alloying elements selected from tungsten, cobalt, niobium, rhenium, molybdenum, tantalum, vanadium, hafnium, yttrium, zirconium and/or other high melting alloying elements.
