20Cr alloy structural steel round bar Equivalent material
20Cr steel round bar should be delivered at hot-rolled or hot wrought conditions. 20Cr alloy structural steel round bar has high strength and hardenability comparing to 15Cr steel, 20Cr alloy structural steel round bar is mainly used for high strength core part manufacturing requirements, the surface to withstand wear and tear, the section in the shape of 30mm or less complex and less load carburizing parts (oil quenching).
