Chromium is included in these alloys,atlevels from1.4 to4%to ensure that the irons solidify carbidic (i.e., to counteract the graphitizingeffectofnickel). Typical microstructure of class I type A nickel-chromium white cast iron.
If chromium, nickel, or some other alloying element is added to the cast iron, the casting may harden throughout its thickness. These alloy additions also provide increased wear resistance in the form of alloy carbides. Iron-chromium hard-surfacing layers are based upon the metallurgy of these white irons. Hardnesses of deposit can range from RC 40 to RC 60.
