3CR12 is a chromium containing corrosion resisting ferritic steel developed as an alternative material of construction where the mechanical properties, corrosion resistance and fabrication requirements of other materials such as mild steel, galvanised or aluminised steel, aluminium or pre-painted steels are unsuited.hen replacing carbon steel with 3CR12, it is necessary to redesign mild and constructional steel components using the mechanical and corrosion resisting properties of 3CR12 in order to gain full advantage of potential material and fabrication savings.
P20, a 4130, 4135 modified material, has long been the steel of choice for pre-hardened mold steels. P20 is classified as a chrome-moly alloy, with a carbon content of approximately 0.30 to 0.40.Over time, many variations on basic P20 chemistry have been introduced to the marketplace.20, a 4130, 4135 modified material, has long been the steel of choice for pre-hardened mold steels.
