42CrMoS4/1.7227 has high yield strength and tensile strength, making it suitable for working environments that bear greater stress and load. 42CrMoS4 has good strength and toughness and can maintain stable performance under vibration, impact load and high stress environment to avoid accidental breakage and damage. 42CrMoS4 alloy steel has good wear resistance and heat resistance, and can be used for a long time in high-speed wear and high temperature environments. 42CrMoS4 material is easy to machine and heat treat, and can be quenched, tempered and other process operations.
42CrMoS4 application areas:
Automotive industry: 42CrMoS4 is often used in the automotive industry to manufacture key components such as bearings, gears, transmission shafts, etc. Because of its high strength and excellent wear resistance, it performs well in components requiring high strength and durability.
Machinery manufacturing industry: Due to the high strength and good toughness of 42CrMoS4, it is often used to manufacture key parts of machinery and equipment, such as construction machinery, excavators, cranes, injection molding machines, etc.
Petroleum and chemical industry: 42CrMoS4 is often used to manufacture equipment and pipes that withstand high pressure and high temperature in harsh working environments, such as pipe connectors, valves, oil well drill pipes, etc.
Energy field: 42CrMoS4 can be used in key components in electric power, aerospace and other fields, such as turbine blades, engine parts, etc.
42CrMoS4 heat treatment method:
1. Quenching: quickly put the 42CrMoS4 heated to a suitable temperature (such as 850-880 degrees Celsius) into the quenching medium (such as water, oil or air) to cool it quickly. Rapid cooling during the quenching process can achieve high hardness and high strength material structure.
2. Tempering: Quenched 42CrMoS4 can be too brittle, so tempering is required to eliminate internal stress and improve toughness. The temperature and time of tempering should be controlled according to specific requirements, usually in a medium temperature range (such as 300-600 degrees Celsius). Tempering reduces hardness but increases plasticity and toughness.
3. Normalizing: Normalizing, also called annealing, is a heat treatment process performed before quenching. Heat 42CrMoS4 to a suitable temperature (such as 850-880 degrees Celsius), then maintain it for a period of time, and finally cool it at an appropriate rate. Normalizing improves the toughness and ductility of the material.
4. Chemical heat treatment: In addition to conventional quenching, tempering and normalizing, 42CrMoS4 can also undergo other chemical heat treatment processes to change the characteristics of the material, such as carburizing, nitriding, etc.
