Brinell Hardness an overview ScienceDirect Topics
For example, automotive disk brake rotors and brake drums are produced from a class 30 Gy iron with a Brinell hardness range of 179–229 kg mm −2 It is usually true that alloy elements are not specified, only as needed to meet the minimum tensile specifications and the Brinell hardness rangeBrinell hardness is a typical hardness specification for cast iron products, especially for ductile iron and gray cast iron However, in the most international standards, cast iron hardness is not a necessary inspection specification Only in Chinese standards, we could see the normal Brinell Hardness (HBS) range for common cast iron gradesCast Iron Brinell Hardness, Ductile Iron and Gray Cast IronBrinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 980665 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 empiricallyBrinell scale WikipediaBrinell hardness iron ore magnetite properties of ironorehardnessron ore wikipedia, the free encyclopediaron is the worlds most commonly used metal etails nihard iron castingsfcihard castings are produced with an abrasion resistant iron with a minimum of 550 brinell hardness, hard white cast iron containing 4 ni and 2Brinell Hardness Iron Ore bastbdeSpecial Cast Iron Grades for Hardness Property : The following gray iron and ductile iron grades are very special, they have specific requirement to the Brinell Hardness range, because the hardness property will affect their performance of using, so the manufacturers must control their hardness in the required range Gray Cast iron (ENGJL) Item according to DIN EN 1561 Wall thickness [mm Special cast iron grades for hardness property
