High Chrome Alloy Grinding Media Balls. High chromium white cast iron grinding balls are also called high chromium alloy casting balls.Most of the wear-resistant materials enterprise use medium frequency electric furnace through the melting of high-quality scrap steel and chromium alloy materials after reasonable matching.What is more,they also use grinding ball metal mold and sand box mould

However, the wide variation in mechanical properties of high chromium white iron castings despite conforming to the chemical specification has been a cause 

One major class of refractory cement additives is that of chrome compounds; chrome flour, chrome sand (chromite) and directly chromium (iii) oxide (chromia, Cr 2 O 3 ). It is stated that 18% of all chromite is used for refractory purposes (9). Chrome-based refractory materials are extensively used in furnace environments for the production of

11/15 · Summary: Chromium-molybdenum alloy steel (or chrome moly ), is an alloy employed for high pressure and temperature use. It’s used in construction, oil and gas, energy, and the automotive industries because of its corrosion resistance and high-temperature and tensile strength. The added reliability provided by chrome moly means it’s the

Chrome white iron is comprised of carbides and martensite. This combination makes chrome white iron exceptionally wear resistant and hard. The carbides in chrome white iron have a hardness range of 1500-1800HV and are primarily eutectic carbides. They form as bundles of hollow hexagonal rods.

The 25% Cr alloy is the most common high chrome white iron poured at Penticton Foundry. This alloy has great abrasion resistant properties 

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

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

The paper presents the results of research on the high-chromium cast irons of chemical composition (in wt. %) 2-4 C, 21-22 Cr, 1-2 Mo, 5-6 Ni, 

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 

High Chrome Alloy Grinding Media Balls High chromium white cast iron grinding balls are also called high chromium alloy casting balls.Most of the wear-resistant materials enterprise use medium frequency electric furnace through the melting of high-quality scrap steel and chromium alloy materials after reasonable matching.What is more,they also use grinding ball metal

The material used in this research was high chromium white cast iron with some main compositions such as 18.5%wt Cr, 2.1%wt C, and 2.8%wt Ni. The heat treatment 

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

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.

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 percent: 2.6-2.8% of carbon, 11.3-12.5% of chrome, 0.1-0.3% of nickel, 0.3-0.5% of

Uses. AISI SAE 4130 alloy steel can be made into steel plate, steel sheet, round and flat steel bar, steel pipe and tube, etc. and has many uses in pressure vessels, pumps and valves, pinions, shaft gears, ball studs, screws, general purpose profile steel, automotive parts, oil and gas industry, aerospace, and bike frame, etc.

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

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.

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.

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.

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
