ASTM 52100 bearing steel, 100Cr6/1.3505, SUJ2, 535A99/EN31 chromium bearing steel detailed chemical composition, mechanical properties and heat treatment.
Bainite Isothermal QuenchingThe application range of GCr15 steel has been expanded. Generally, the effective wall thickness of the ring is below 12mm when GCr15 steel M is quenching.however, due to the strong cooling capacity of nitro salt in BL quenching, the effective wall thickness of the ring can be expanded to about 28mm if mixing, stringing and adding water are adopted.
The invention discloses a heat treatment method of GCr15 steel. The heat treatment method comprises the following steps of:heating the GCr15 steel to 1045-1055 DEG C, and after insulating for 0.4-0.6 hour, carrying out quenching treatment in oil; cooling to room temperature, heating to 715-725 DEG C and carrying out tempering treatment; cooling to room temperature and then carrying out

Constitutive modeling for flow behavior of GCr15 steel Jan 01, 2013 · A commercial GCr15 high-chromium bearing steel commonly used for manufacturing bearing ring was investigated in this paper. The chemical composition of the GCr15 steel used in this study is shown in Table 1.Hot compression experiments were conducted on the Gleeble-3500 thermo-simulation system as shown in Fig. 1. Fig. 1a is the mechanical part of the Gleeble-3500 thermo
DIN 1.3505 Material 100Cr6 Bearing Steel Equivalent Hardening temperature:830-870 , quenching media:oil. Tempering temperature:150-180 . Equivalent Grades. DIN EN 1.3505 steel, 100Cr6 material equivalent to US ASTM AISI SAE, Japanese JIS, and Chinese GB standard.
Nov 01, 2017 · The GCr15 steel's microhardness and residual stress distribution along the depth from the surface to core were measured by the corresponding machinery. Microhardness measurement was conducted by means of FM-700 Vickers hardness tester at an applied load of 100 g with PC controlled.
High carbon chromium bearing steel GCr15 and GCr15SiMnHigh-carbon chromium bearing steel is widely used in the world, the most commonly used types are GCr15 and GCr15SiMn, accounted for about 80% of the total amount of bearing steel in China, the performance of the two kinds of steel is basically the same, but the quenching permeability of GCr15SiMn is better than GCr15, so for larger size bearing
History and Properties of 52100 Steel - Knife Steel NerdsJan 28, 2019 · Quench Speed One purpose of the Cr addition is for hardenability, a measure of how fast steel must be quenched from high temperature to achieve full hardness. A simple carbon steel such as 1095 requires a very fast water quench to fully harden, where a hard steel phase called martensite is formed. 1095 has nearly 1% carbon like 52100 but
Three groups of GCr15 steel were heat-treated respectively by conventional spheroidizing annealing, circulation spheroidizing annealing, 1050°C for 30min oil cooling quenching + 700°C tempering. The final heat treatment of these GCr15 steel was 840°C oil cooling quenching + 150°C tempering. The microstructure of the heat-treated GCr15 were observed and the mechanism of three spheroidizing
