Chinese GB Standard - Page 3 of 4 - World Material

40Cr Alloy Steel 40Cr steel is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades. For 40Cr material hardness, specifications and equivalent, please see the table below. Galvanic Corrosion Between Depleted Uranium and 40Cr values of DU and 40Cr steel in 3.5wt.% sodium chloride solution after 1h, 24h and 48h immersion, respectively. As can be seen from table 1, the R p value of 40Cr steel is larger than that of DU during the first corrosion period, which indicates that 40Cr steel shall be more anti-corrosive in 3.5w.t%NaCl solution at this time. Superior mechanical properties of 40Cr steel obtained by Jan 20, 2020 · Jan 20, 2020 · 1. Introduction. The improvement of mechanical properties has been a key topic in steel research for centuries [1,2].Quenching, which can induce a combined strengthening effect of solid solution strengthening, phase transformation strengthening (dislocation, stacking faults and twins), and boundary strengthening (lath, packet, and prior austenite grain boundaries), has been

40cr steel pipe characteristics and the purpose

40cr pipe belong to the nitride steel pipe, which contains elements conducive to nitride. 40cr pipe after the nitriding treatment to obtain a higher surface hardness, the hardness of the nitriding treatment in the 40cr pipe quenched after highest attainable HRA72 ~ 78, i.e. HRC43 to 55. Nitride workpiece process route:forging - annealing
