Chromium, Cr, 0.80 - 1.10 % ; Iron, Fe, 96.785 - 97.77 % (As remainder) ; Manganese, Mn, 0.75 - 1.0 % ; Molybdenum, Mo, 0.15 - 0.25 %.

Hard chrome has a very low coefficient of friction. Applying a surface finish, like hard chrome, would greatly reduce friction, therefore increasing the service life and performance of the parts.

Commonly called chrome, the alloy referred to here is actually chromium. Chromium is added to steel in small quantities to improve strength, corrosion resistance and response to heat

The main raw material to manufacture high chrome refractory brick is sintered magnesia and chromite. Purity magnesia raw material to be as high as possible, the requirements of the chemical composition of chromite is: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.

Nickel/chromium alloys containing more than 30% chromium have a two phase structure which consists of a -chromium and γ-nickel. The a -chromium phase brittle and hence the alloy decreases in ductility with increasing chromium content. Properties for some binary alloys are given in table 2.

HC27 is a modified High Chromium White Iron developed to provide the highest degree of toughness while retaining excellent abrasion resistance. This.

High chromium white cast iron alloy used in coal grinding components is a material that may present different wear resistance depending on the thermal treatment 

The high-chrome wear-resistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and

Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium metal is valued for its high corrosion resistance and hardness.A major development in steel production was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic

The high-chrome wear-resistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and copper as

It has a microstructurethat contains an addition of Nitrogen, Nickel, and Manganese. The construction of austenitic chrome steel is similar as what you would find in common steel. But solely in a much larger temperature giving it formability and weldability.

Wear Resistant Irons are also referred to as High Chrome Alloys, Abrasion Resistant Irons, White Irons and Ni hard. This family of materials has been 

Nickel-Chrome-High Carbon Alloy This material may also be called Ni-Hard 1. Ni-Hard 1 is an abrasion resistant material used in applications where impact is also a concern as the wear mechanism. Ni-Hard 1 should also be considered if there are low or medium dynamic stresses.

High-chromium irons have good mechanical properties, high hardness in a cast state, low fluctuation of hardness when properties change. High-chromium irons almost don’t concede in fluidity to regular gray cast iron that allows using parts sufficiently difficult form directly after casting without the following machining.

The invention discloses a high chrome alloy steel material and a preparation method thereof. The high chrome alloy steel material contains the following chemical elements by mass

High chromium white cast irons are an important class of wear resistant materials. Their exceptional wear resistance is the result of their high carbide content, which forms along with austenite during solidification as a pro-eutectic or eutectic phase depending on alloy composition, and particularly depending upon carbon and chromium content.

High Chrome A05 Alloy The microstructure of High chrome alloy A05 (27 Cr) shown in Figure 1(a) consists of hard eutectic chromium carbides in a fully hardened martensitic matrix. The material is covered by a number of different Internationally recognised standards including: ISO 21988 Grade 25Cr, AS 2027 Grade 27Cr; BS 4844 Grade 3D and ASTM

25% Chrome Tough Alloy. This alloy maintains the abrasion resistance of the 25% chrome alloy with increased toughness. This alloy is used for thicker section castings exposed to a high impact environment, such as in mining and crushing and in the Alberta Oil Sands . Castings poured with this alloy can be machined, but not drilled or tapped.

1/13 · ASTM A532 Class III Type A. The 25% Cr alloy is the most common high chrome white iron poured at Penticton Foundry. This alloy has great abrasion resistant properties

Superior grinding performance High-Chrome media combining a martensitic structure with hard chrome carbides provides the optimum wear resistance against abrasion and corrosion. Our strong expertise is enabling us to select the right alloy to fit your application and minimize the costs. Steady milling conditions due to low wear rate Constant hardness of all grinding media

Chromium oxide is the main component of the phosphate added high-chrome refractory. Spinel solid solutions were the main reaction products at the interface between the high-chrome refractory and the slag ( Table 7 ), thus confirming the formation of spinel solid solutions. Anorthite was the crystal phase in the slag ( Table 6 ).

High Chrome Steel Rolls HiCr Steel is characterized by excellent fire crack resistance and very good oxidation behaviour at rolling temperature. Very good wear resistance and constant material properties throughout the shell layer. HiCr Steel is manufactured by horizontal spin casting.
