20CrNiMo was originally steel number 8620 in the American AISI and SAE standards. The hardenability performance is similar to that of 20CrNi steel. Although the Ni content in the steel is half that of 20CrNi steel, due to the addition of a small amount of Mo element, the upper part of the austenite isothermal transformation curve moves to the right; and due to the appropriate increase in Mn content, the hardenability of this steel is still very good, and the strength It is also higher than 20CrNi steel, and can also replace 12CrNi3 steel to manufacture carburized parts and cyanide parts that require higher core performance. 20CrNiMo can withstand a certain temperature in addition to good comprehensive properties because it contains molybdenum.
1. In the manufacturing industry, it is often used to manufacture parts that are subject to high load, high stress, and high wear, such as gears, shafts, bearings, etc. Their high strength and good toughness enable these parts to maintain a long service life in harsh working environments. In addition, it also has excellent fatigue resistance and corrosion resistance, which can effectively resist the erosion of the external environment and ensure the stable operation of the equipment.
2. In the field of construction, this steel is widely used in the construction of large structures such as bridges and high-rise buildings due to its high strength and good ductility. In these structures, they can withstand huge pressure and tension, ensuring the safety and stability of the building.
3. In addition, with the improvement of environmental awareness, applications in the field of environmental protection are becoming more and more extensive. For example, in new energy vehicles, it can be used to manufacture key components such as motors and reducers, contributing to green travel. It also plays an important role in environmental protection equipment such as sewage treatment and waste gas treatment, providing strong support for improving environmental quality.
1. Important structural components, such as aircraft landing gear, tanks and armored vehicle components.
2. High-strength fasteners and connectors.
3. High load gears and bearings.
Quenching 850ºC, oil cold; Temper 200ºC, air cooling.
Delivery in heat treatment (normalizing, annealing or high temperature tempering) or no heat treatment condition, the condition of delivery shall be indicated in the contract.
Being supported by an highly developed and specialist group, we could supply technical support on pre-sales & after-sales service.
