the class i type d (ni-hard 4) alloy is a modified nickel-chromium iron that contains higher levels of chromium, ranging from 7 to 11% and increased levelsofnickel,rangingfrom5to7%. whereastheeutecticcarbidephaseinthe lower-alloyed nickel-chromium irons is m3c (iron carbide), which forms as a continuous network in these irons, the higher

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

Oct 01,  · High chromium cast irons (HCCIs) (with 12–30 wt% Cr and 1.8–3.6 wt% C) have been widely used in the mining and mineral processing industry for their good properties of wear resistance [ [1], [2], [3], [4], [5], [6], [7] ].

The mechanical properties such as impact initiation, bending strength, macro and micro hardness of the composites under the bimetal liquid lost foam casting process are

Mar 07,  · 1. Introduction High chromium cast irons (HCCIs) are primarily used in mining machinery, wear resistant lining board, crusher jawplate, etc. because of their excellent wear

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 

Jun 22,  · High-chromium (25 – 35% Cr) cast irons are recommended during operation in oxidizing acids, especially in nitric acid. They exhibit good corrosion resistance in sulfuric acid of any concentration at temperatures up to 80°C, and in phosphoric acid at a concentration ≤ 60% up to the boiling temperature and with a concentration of ≤ 85% up to 80°C.

Description Wear-resistant high chromium cast iron pipes are composed of 2 layers of metal, the outer layer is generally Q235 ordinary steel pipe, and the innerHigh chromium alloy,Optional welding and cutting, high wear resistance and heat resistance.

High chromium cast iron is one of the wear resistant materials used in a variety of applications where stability in an aggressive environmental is a principal requirement. These applications include slurry pumps, brick dies, several pieces of mine drilling equipment, rock machining equipment, and similar areas [ 1, 2 ].

1. Introduction High chromium hardened white cast iron (HCWCI) is widely used in processes having high mechanical requirements and wear resistance but having limited toughness. Its wear resistance is directly linked to its microstructure and the addition of alloy elements [ 1 ].

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.

Jul 23,  · High-chromium cast iron (HCCI) has been widely used for wear-affected equipment and operating conditions, such as wear-resistant lining board, crusher jaw plate, mining and mineral machinery processing, and oil sands handling [ 3, 4, 5, 6 ]. The good wear resistance of HCCI is due to the lots of (Fe,Cr) 7 C 3 carbides [ 7, 8, 9 ].

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

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.
