how to harden a36 steel

  • How to Heat Treat A36 Steel Career Trend

    Dec 27, 2018 · A36 grade steel is considered low alloy; however, because the carbon can range up to 0.29 percent at the most and mild steel is anything below 0.25 percent, A36 is considered the safest mild steel. As such, direct heat treating is not applicable. Case hardening is the process for treating A36 steel.Read More
