This material is classified under letters G to J of the Unified Numbering System. Maraging (“MAR-aging”) forms of this material contain hard precipitate particles over an artificially elongated aging period. Modern manufacturing of this material uses a supersonic oxygen jet and burnt lime to generate a basic slag. Case-hardening of this material can be accomplished using carburization. Rapidly quenching one form of this material produces crystalline martensite. Hot-dip and electrogalvanization are methods for plating this material to prevent corrosion, which can also be accomplished by adding chromium. For 10 points, name this alloy of iron and carbon that includes a stainless variety. ■END■
