cold rolled steel is mild steel, or very close in carbon content. it's rolled cold rather than hot rolled. it is slightly more resistant than is h,r. mild to oxidation. i don't think there is a mild form that wont take up oxygen.Hello thanks for the suggestion, but could you indicate me a type of soft steel and with little oxidation. I've used SAE 1020 1045 is very soft with 0.2% and 0.4% carbon.
I would like a mild steel that does not rust. Does anyone know what kind of steel the mint uses to engrave their stamp and cell dies?
Thanks
