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

3/21 · Grey cast iron or commonly cast iron are used for large number of cast irons having graphite flakes in ferritic or Pearlitic matrix. These cast iron types are developed by equilibrium or slow cooling. Cast iron types of these types normally contain 2.4% to 4% carbon, 1% to 3% silicon, and small amount of magnesium with range in-between 0.1% to

It was found that the primary carbides in the hypereutectic high chromium cast iron were all refined to different levels after different 

High-chromium white iron alloys allow massive castings (for example, a 10-tonne impeller) to be sand cast, as the chromium reduces cooling rate required to produce carbides through the greater thicknesses of material. Chromium also produces carbides with impressive abrasion resistance. [citation needed]

The research reported in the paper concerned the conditions of cooling high-chromium cast iron with about 15% Cr content capable to ensure 

high chromium white cast iron alloys, including their classifications, their standard specifications in USA, China and Australia, their main usages and the 

8/28 · Due to the high content of chromium in the alloy, it is easy to form a film on the surface of the molten iron, so the liquid iron seems to have poor fluidity, but in fact, the fluidity

abrasion resistance attainable among the white cast irons. ❖. In the high-chromium irons, as with most abrasion-resistant materials, there.

Halnn Solid CBN Inserts process high chromium cast iron cast iron itself hardness is not high , we commonly choose Brinell hardness (between HB170~210). For the factory of processing gray cast iron parts with small batch production, people will choose carbide insert which will be more economic, such as YG series.

High chromium cast iron (containing 12% chromium >) is an excellent wear resistant material.In the research of high chromium cast iron, generally focus on high chromium cast iron such as Cr15, Cr20.With the increase of Cr content and the addition of various alloying elements, the influence on the change properties of the structure was studied.

High chromium white cast irons (HCWCI) are known as abrasion-resistant cast irons and represent one of the most complex microcomposite 

Enhanced High Chromium Cast Iron Roll (En-HiCr) Enhanced high chromium cast iron roll is widely applied as work roll of the front stand of HSM. The constitutions are characterized by 20-30% of M7C3 carbides of great hardness evenly distributed in the matrix of tempered Martensite so that the durability and anti-thermal fatigue performance are

Chromium is a powerful carbide stabilizing element, which can be achieved just by proportionally small concentrations a carbide formation within the ductile iron which is only difficult to remove by heat treatment.

Carbon · 2.69 % ; Chromium · 10.51 % ; Copper · 0.63 % ; Manganese · 0.65 % ; Molybdenum · 0.5 %.

Medium chromium white cast iron and medium chromium-silicon white cast iron (both belong to KmTBCr8) have been widely used in China. The main features of these irons are the alloying of carbon and chromium to give a ratio of Cr/C ≈ 3, and the formed eutectic carbide is of the type M7C3, thus giving the irons an excellent combination of properties and higher

The initial as-cast microstructure of high-chromium white cast iron (2.08% C, 12.1% Cr), including austenitic dendrites in a matrix of a eutectic mixture of austenite and M7C3 carbides.

WSF can produce for you a 15% and 25% Hi-Chrome alloy iron. Typically used in applications of wear resistance and long term heat resistance are required, such as impellers, turbines, and grinding applications. The iron expresses a very hard surface. These high-chromium alloys attribute their superior hardness to the presence of chromium

2/3 · 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 ].

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 

It has been proved that an addition of boron carbide and shredded steel scrap introduced as an inoculants to the chromium white cast iron changes the 

1/23 · Conclusions. 1. For high boron white cast iron, with the increase of chromium, the microhardness of boride increases, and the morphology of boride changes from continuous network to less continuous distribution. 2. With the chromium increase, martensite appears in the matrix, and its volume percentage increases.
