Such rolls have high tensile strength and small hardness drop as well as better hot tear resistance, fatigue resistance and wear
Main performance and applications: Multi-alloy elements are adopted for such rolls for increasing the hardness value under the situation of high tensile strength. Therefore such rolls have high tensile strength and small hardness drop as well as better hot tear resistance, fatigue resistance and wear resistance.
Major applications: roughing roll for section steel, vertical roll, etc..
