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. (10[2])Case-hardening of this material can be accomplished (-5[1])using carburization. Rapidly (10[1])quenching one form of this material produces crystalline martensite. (10[2])Hot-dip (-5[1])and (10[1])electrogalvanization are methods for plating (-5[1])this (10[1])material to prevent corrosion, which can also be accomplished by adding chromium. For 10 points, name this alloy of iron and (10[1])carbon that includes a stainless variety. ■END■ (10[2])
