40CR Steel - Practical Machinist

Mar 09, 2019 · 40Cr steel is a kind of Chinese alloy steel, and one of the most widely used steel grades in China. For more information, please see 40Cr steel properties, specification and equivalent . 03-09-2019, 11:10 AM #7 40Cr Alloy Structure Steel - Special steel china supplier GB 40CR alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc. GB 40CR steel Annealing delivery hardenss less than 250HB.40CR With a lower carbon content range, So GB 40CR alloy steel have good weldability.

40Cr Quenched and Tempered, What is the Hardness vs

Aug 01, 2016 · As far as I could find, the steel grade 40Cr corresponds to the steel grade 40X (standard GOST 8479-70, forged steel; 0.36-0.44 wt% C, 0.17-0.37 wt% Si, 0.50-0.80 wt% Mn, 0.80-1.10 wt% Cr). 40Cr Scientific.NetAbstract:40Cr is a kind of steel that is often used for semiaxis in heavy duty trucks, therefore high impact property of 40Cr steel is requested to adjust the heavy-duty machines working environment. In this study, the samples of 40Cr steel were heated under normal tempering temperature and quenched in air, water and oil, respectively. 40Cr Steel Material Sheet Plate Round Bar - Songshun Steel40Cr Mechanical Properties. Tensile Strength: 810 MPa; Yield Point: 785 MPa; Impact Absorbing Energy: 47 J; What is 40Cr Steel Material Used for? It is one of the most popular steel grades in the industry. After Q+T heat treatment, it usually is used to make parts. Such as the gears of machine tools, shaft, worm, spline shaft and etc.
