CHROME STEEL BALLS DESCRIPTION Chrome steel balls are widely used in high speed ball bearings, valve industry, as well as, in a number of other industrial applications. Chrome steel balls have excellent surface quality, high hardness, high load bearing capacity and wear resistance, as a result of through hardening.
HIGH CHROME CAST STEEL BALLS High Chrome Steel Balls can be used for many different applications. They are available in two grades—10–13% chrome (surface hardness ≥ 60 HRC, core hardness ≥ 58 HRC), and 14–18% chrome (surface hardness ≥ 62 HRC, core hardness ≥ 60 HRC).
Superior grinding performance HighChrome 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 for each alloy ...

Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, m/s 2, to convert it to megapascals. The BHN can be converted into the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically.
Jan 13, 2016· 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 especially against gouging, grinding and scratching. 25% Cr material can be machined to meet tighter tolerances like those found in pump and piping type castings.
Stainless Steel Hardness Test Method and Conversion Table. ... which is tested by using specific materials and shapes such as diamond ball or cone among others. ... thus obtaining the Brinell hardness number of the material. The Rockwell test is a little more complex. It involves different scales identified with capital letters.
* Values based on Brinell 10mm Standard Ball (3000kgf). ** This conversion calculator gives approximate hardness values for various hardness scales based on the Rockwell "C" Scale. The Hardness Tensile Strength relations may vary according to the processing history or the chemical composition of the steel.

brinell hardness chart printable pdf Convert Brinell Indentation Measurements to Brinell Numbers for 3000,1500,500 kg loads etc and for 10mm or 5mm Brinell ball diameters
Hardness. Because it is composed of a combination of high chrome and high carbon, chromium carbide steel plate achieves unparalleled hardness. When the two metals join forces, they form chromium carbide crystals that reach 600 BHN on the Brinell hardness scale.
BHN = Brinell Hardness Number. P = load on the indenting tool (kg) D = diameter of steel ball (mm) d = measure diameter at the rim of the impression (mm) It is desirable that the test load are limited to a impression diameter in the range of to mm. Approximate loads and Brinell Hardness Numbers:
