4150 Hot Rolled SBQ Bar

Hot rolled 4150 steel bar is a medium/high-carbon alloy steel that contains chromium and molybdenum. Hot rolled 4150 round bar is known for its increased hardenability and mechanical properties. The machinability of 4150 steel bar is better in the annealed form. Eaton Steel Bar Company stocks many diameters of 4150 hot rolled steel to meet the market demands. We also supply 4150 hot rolled round bar to various industries like aerospace, automotive, firearm, and tooling.
