WebMar 8, 2004 · Effect of hardness, residual stress and grain size on the fatigue life of ultra-clean bainitically hardened bearing steel T. Meyer Materials Science 2012 Ultra clean, high carbon, bainitically hardened steel grades are used in large sized bearings where demands on fatigue properties are very high. WebOct 30, 2015 · The relationships between the hardness and the distance from the surface of the carbonitrided specimens are shown in Fig. 8. The hardness is high at the surface, decreases with increasing depth, and becomes stable at a depth of approximately 700 μm, i.e., a total case depth.

WebFeb 28, 2024 · The carbonitriding process alters the top layer of the component so the original dimensions are retained. This case hardening is typically between 0.07 – 0.75mm thick. A thicker case means more … WebAug 15, 2024 · The most common bearing steel used for through hardened bearings is AISI 52100 or equivalent. This is a high carbon steel (approx 1.0%) and is hardened by a Martensitic or Bainitic process. Through hardened bearings made of 52100 steel, have a resulting hardness of approximately 60HRC. download divx converter
