What's the price of 42CrMoS4 steel alloy
Steel pipe 42CrMoS4 steel alloy manufacturing, environmental protection equipment and other manufacturers supply steel products, which have been well received by new and old customers. Steel sales have maintained a strong growth momentum and have achieved a good reputation in the steel industry. The 42CrMoS4 steel alloy company has a young, energetic and service spirit, high-quality management team.
45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel 42CrMoS4 steel alloy is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.
The difference between 42CrMoS4 steel alloy, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.
Phosphorus is a very harmful element in 42CrMoS4 steel alloy steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of 42CrMoS4 steel alloy steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
