What is the 25CrMo4 steel material heat treatment

The company adheres to the 25CrMo4 steel material external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of 25CrMo4 steel material quality and price and best service for all our customers.

25CrMo4 steel material, Wear resistant steel plate has been used in many fields, and its roughness requirements are different for different applications. In the process of production, the roughness of production equipment such as the work roll of leveller will be shown on the surface. It has been proved that both the roughness of work roll surface and the rolling force have influence on the roughness value of tube surface, and there is a nonlinear positive correlation.

Spring steel, as we can clearly know from its name, is one of the main materials used to make springs and special alloy steel for other elastic components. 25CrMo4 steel material, Spring steel has good comprehensive properties, it has heat resistance, low temperature resistance, oxidation resistance, corrosion resistance and so on advantages. Compared with alloy spring steel, carbon spring steel has less advantages, but its price is cheaper, and the source of raw materials is convenient. The disadvantage of carbon spring steel is that the elastic limit is low and it is easy to lose elasticity after repeated deformation.

The wear-resistant layer of wear-resistant steel plate is mainly composed of high-carbon and high-chromium alloy. According to the requirements of different users and service conditions, 25CrMo4 steel material, the high-temperature wear-resistant steel plate also contains alloy elements such as Mo, W, V, B, Nb, Ti, etc. The microstructure of the wear-resistant layer is eutectic + M7C3-secondary carbide or complex carbide. It can achieve high wear resistance of normal temperature, high temperature, strong impact, medium impact, and low stress impact.

Chemical composition differences between the 25CrMo4 steel material, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
