ASTM 52100 Bearing Steel 100Cr6 SUJ2 EN31 - Otai

ASTM 52100 bearing steel, 100Cr6/1.3505, SUJ2, 535A99/EN31 chromium bearing steel detailed chemical composition, mechanical properties and heat treatment. Austenite grain growth behavior of a GCr15 bearing steel Isothermal homogenization heat treatments for a GCr15 bearing steel cast billet were performed at temperatures of 10001250 °C and holding times of 30180 min.

Common Problems in Bearing Heat Treatment Process

Aug 01, 2019 · 1) Heat treatment deformation. When the bearing parts are heat treated, there are thermal stress and tissue stress. This internal stress can be superimposed or partially offset, which is complex and variable. Since it can vary with heating temperature, heating rate, cooling method, cooling rate, part shape and size, heat treatment deformation Directly spheroidizing during hot deformation in GCr15 steelsMar 20, 2008 · The spheroidizing heat treatment is normally required prior to the cold forming in GCr15 steel in order to improve its machinability. In the conventional spheroidizing process, very long annealing time, generally more than 10 h, is needed to assure proper spheroidizing. It results in low productivity, high cost, and especially high energy consumption. GCr15 Bearing Steel - Fushun Special Steel Co., Ltd It also has characteristics of a wide scope of plasticstable heat-treatment quality, uniform, and high hardness, high wear resistancehigh strength of touching fatigue. It has excellent machining property after spheroidize annealing. GB GCr15 bearing steel is GB standard Alloy Bearing steel, It belong to the high-quality high carbon, alloy
