High-chromium white cast irons are ferrous alloys containing 11-30% Cr and 1.8-3.6% C along with variable amounts of molybdenum, manganese, copper and nickel [1]. The standard procedure most commonly used for the classification of this kind of cast iron

High Chromium Casting, High-chromium alloy casting and forging, high-chromium castings is called high-chromium casting or steel castings, and is a chromium-based white cast iron. It is a kind of grinding medium among ordinary white cast iron and nickel hard white iron developed from the third generation of chromium-based wear-resistant materials.

The objective of the present work is to establish the heat treating parameters necessary to impose to a pair of high chromium white cast irons a hardness figure in the range from 35 to 40 HRC, acceptable to guarantee a reasonable machinability of the material. Samples of two high chromium white cast irons have been isothermally annealed under

In mining, wear is caused by operational problems in which generate high costs. Some researchers studied white cast iron alloys with high 

KmTBCr15Mo is a type of high chromium white cast iron, which has been studied deeply and is widely used. It is normally air quenched and tempered and has high hardness, strength, and toughness, with excellent resistance to corrosion and impact abrasion. KmTBCr20Mo iron has high chromium content and thus a higher Cr/C ratio; hence, it has better

High-Chromium White Irons, The high-chromium white irons have excellent abrasion resistance and are used effectively in slurry pumps, brick molds, coal-grinding mills, shot-blasting equipment, and components for quarrying, hard-rock mining, and milling. In some applications they must also be able to withstand heavy impact loading.

Bell advertised for sale: "A cast center lever plow, 100 bells, made from the best materials at the foundry." The also had on hand a number of improved beehives and were prepared to pay cash for any amount of scrap iron. In 1869 Bell purchased Marlay's interest and continued to add various items to those he already sold and manufactured.
