What is the alloy elements in the role of cold roll material?

2013/12/5??????view:
In the 86CrMoV7 work roll, C is an important alloying element in steel, mainly through the solution in the steel matrix, the steel reinforcement; while the other part of carbon and carbide forming elements in steel carbide formation, distributed in the steel matrix, to strengthen and increase the role of.Cr wear the role is to increase thehardenability, increase the strength of steel and corrosion resistance, and he and carbon to form M3C or M7C3type carbides, effectively increase the wear resistance of roller; the role of Mo is to increase the roll hardenability,significantly increase the strength of steel, eliminate roll temper brittleness; V effect for the grain refinement of steel roller, increase the hardenability and strength, at the same time by grain refinement to increase the toughness and plasticity.
