CN102071291A - Hardening and tempering method for alloy

The alloy steel 40Cr steel plate with the thickness of 80 mm below comprises the following chemical components in percentage by weight (wt%):0.38 to 0.43 of C, 0.20 to 0.35 of Si, 0.60 to 0.75 of Mn, less than or equal to 0.018 of P, less than or equal to 0.010 of S, 0.85 to 1.00 of Cr, 0.005 to 0.015 of Als, and the balance of Fe and residual elements. Heat Treatment Process of Automobile Half ShaftHere, 40Cr is taken as an example to briefly describe the technical requirements for surface hardening of the semi-shafts:quenching The hardness of the pre-tempered matrix is 321375 (HBS), the hardness after quenching reaches 4558 (HRC), the hardness after tempering is required to be 4550 (HRC), and the depth of the hardened layer is between 2.55mm. Heat Treatment of C45 Plate - BEBON InternationalC45 plate belongs to high quality carbon structure steel. Do you know the heat treatment of C45 plates, the hardening, quenching and tempering? For heat treat of C45 plates, please check it below. Heat treatment of C45 plates:1. Prior to the C45 plate hardening without tempering, hardness of HRC55 (up to a maximum of HRC62) is qualified.

How Can the Surface of KOYO Bearing Steel be

Common grades are 35 (jrMn, 42CrMo, 35L:rMnV, 40CrMn, 35CrMnSi, 30CrMnsi, 35 (:rMnTi, 40crMnTi, 40crNi, etc.), chromium-molybdenum steel has high hardenability, high temperature strength and good structural stability, eliminating the return Fire brittleness and other characteristics, 42CrMo is used to manufacture quenched and tempered parts with high strength and large cross-section, such as gears, Learn About Quenching & Tempering Clifton SteelSteel is strong to begin with, but sometimes its necessary to make it even stronger. One of the common treatments to achieve this is quenching and tempering. This is a process that strengthens and hardens iron-based alloys by heating, rapidly cooling, and reheating. Oil Drill Pipe Quenching and Tempering-Zhengzhou Gou's Our company uses the new process of quenching and tempering, greatly enhancing the oil drill pipe's wear resistance, corrosion resistance and fatigue resistance, improving its mechanical properties. This equipment is used in the production line with simple structure, simple operation, more scientific and
