Non-standard bearing steel smelting purity requirements

Non-standard bearing steel smelting purity requirements source: bearing | last updated: - 2020 10 - 26 of non-standard bearing steel smelting purity requirements of non-standard bearing steel smelting have particularly stringent purity rules contained in the purity of steel is steel nonmetal material and how much is sundry, pure value is higher, the lower the non-metallic materials of steel and sundry. Non-standard bearing steel in the harm and sundries such as metal oxide, aluminum silicate is a non-standard bearing early fatigue peeling, significantly reduce the non-standard bearing service life of the key. Especially the ductility and sundry harm is bigger, because in the process of production is very easy to fall out from the metal base material, more serious damage to the deep processing of non-standard bearings components after the process performance. Therefore, in order to better promote non-standard bearing life and credibility and be sure to reduce and sundry ingredients in the non-standard bearing steel. Read this article also browse: non-standard bearing steel smelting microscopic have stringent requirements of non-standard bearing steel smelting (institutions and microscopy at high magnification Low power) Agency rules of non-standard bearing steel high institutions is generally loose, loose management center and flat, microscope ( Low power) Institutions include steel quenching institutions, cementite mesh structure, belt strip and liquid chromatography, etc. Cementing fluid analysis harder and more brittle than its bad influence and ductility and sundry also. Network cementite reduce the fracture toughness of steel, and made it the agency is not symmetrical, very easy to deformation and crack during heat treatment. With strip cementite harm quenching and quenching heat treatment institution and touching fatigue limit. Low, the stand or fall of low power institutions could turn to the characteristics of non-standard bearing and have the very big harm, therefore, in the non-standard bearing raw material in the specification of low, low power agencies have strict rules.
