8620 Hot Rolled SBQ Bar

Hot rolled 8620 steel is a low carbon, low alloy grade that contains nickel, chromium, and molybdenum. It has good carburizing properties and formability. The alloy content supports carburizing, improving surface hardness and wear. Eaton Steel Bar Company stocks various diameters of 8620 hot rolled steel to meet the market demands. We also supply 8620 steel bar to various industries like aerospace, agriculture, and automotive.
