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 (-5[1])and burnt lime to generate a basic slag. (10[1])Case-hardening of this material can be accomplished using carburization. (10[2])Rapidly quenching one form of this material produces crystalline martensite. (10[2]-5[1])Hot-dip and electrogalvanization (10[1])are methods for plating this material (10[1])to prevent corrosion, (-5[2])which can also be accomplished by adding chromium. (10[1])For 10 points, name this alloy of iron and carbon that includes a stainless variety. ■END■ (10[4])
