Properties of 34CrMo4 steel

High strength: The chromium element in 34CrMo4 steel can improve its tensile strength, and the addition of molybdenum element can improve its fatigue resistance, so 34CrMo4 steel has high strength characteristics.

Good heat resistance: 34CrMo4 steel can work at high temperature, its material performance will not decrease with the increase of temperature, and can withstand the use requirements of high temperature environment.

Good fatigue resistance: Due to the addition of molybdenum, 34CrMo4 steel has good fatigue resistance and can maintain stable performance under extreme working conditions.

Good processability: 34CrMo4 steel can be processed into various shapes. In addition to the conventional processing technology, it can also be processed by heat treatment, quenching, annealing and other processes.

Good weldability: Some alloy elements in 34CrMo4 steel will affect its weldability, but in the case of avoiding excessive cooling and hardening, 34CrMo4 steel can still carry out various welding methods such as fusion welding and arc welding.

It should be noted that the cooling rate and heat treatment temperature need to be strictly controlled during the use of 34CrMo4 steel, and anti-corrosion and shock-proof treatment should be carried out under high temperature and high pressure environment to ensure its performance and service life.

In summary, 34CrMo4 steel is a high-strength low-alloy steel with high strength, high toughness, high heat resistance and fatigue resistance. 34CrMo4 steel is a structural material widely used in machinery industry, petroleum exploration, chemical industry, automobile, aviation and other fields.
