High chromium cast irons (HCCIs) are alloys containing 15–30 wt. % Cr and 2.5–4 wt. % C, and belong to the Fe–C–Cr ternary system, as described 

In the present work, high chromium cast irons (HCCIs) with different high carbon ferro-chrome (HCFC) content were cladded on a low carbon steel (LCS). The microstructure and mechanical properties

The mechanical properties of High chromium cast iron HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). The hypereutectic HCCI with large volume fractions of hard carbides is preferred to apply in wear applications. However, the coarser and larger primary M7C3 carbides will be precipitated

High chromium cast irons (HCCI's) exhibit very good mechanical properties and offer benefits for a range of manufacturing applications.

Uses of iron Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese. These are used to make bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels. Cast iron contains 3-5% carbon. It is used for pipes, valves, and pumps.

High Chromium White Cast Iron, or High Cr White Iron grades are used in wear applications that require some corrosion resistance. One common application using 

With respect to mechanical properties (σ r = 480 MPa; hardness 290 -340 HB) high-chromium cast iron surpasses high-silicon cast irons . In as number of cases chromium cast irons are additionally alloyed with molybdenum. Molybdenum in white cast iron is within eutectic carbide and matrix phase.

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.

Conclusions · 1. Austenite in high-chromium cast irons is stable up to 500°. · 2. The resistance of high-chromium cast iron to hydroabrasive wear is minimal in 

The hardness of unalloyed high chromium white cast iron is highest amongst all the alloys tested, however, Ti and V additions to it retained this hardness to almost the same extent. V addition to the alloy showed not only highest tensile strength but also longer elongation to fracture, thereby, resulting as toughest alloy in the lot.
