ALLOY STEEL FOR ROLLERS, BEARINGS, AND BUSHINGS IN GALVANIZING SYSTEMS, SUCH ROLLERS, BEARINGS, OR BUSHINGS, AND METHOD FOR PRODUCING SUCH ROLLERS, BEARINGS, OR BUSHINGS

摘要

Alloy steels are known which contain nitrogen, carbon, tungsten, cobalt, vanadium, niobium, molybdenum, chromium, and manganese in addition to iron. Said steels however are frequently not suitable for use as rollers, bearings, or bushings in galvanizing systems due to an insufficient corrosion and wear resistance. A steel is therefore proposed which contains 0.5 to 2 wt.% nitrogen, 0.5 to 1.5 wt.% carbon, 5 to 15 wt.% tungsten, 2 to 7 wt.% cobalt, 2 to 7 wt.% vanadium, 2 to 7 wt.% niobium, 2 to 10 wt.% molybdenum, 3 to 13 wt.% chromium, 5 to 15 wt.% manganese, and the remainder iron. Said steel can be produced inexpensively and is outstandingly suitable for use in galvanizing systems.
