	Main characteristics	Application examples
20CrNiMo	20CrNiMo steel is originally the steel grade 8720 in American AISI and SAE standards. The hardenability is similar to that of 20CrNi steel. Although the content of Ni in steel is half of that of 20CrNi steel, the upper part of the isothermal transformation curve of austenite moves to the right due to the addition of a small amount of Mo; also Due to the proper increase of Mn content, the hardenability of this steel is still very good, and its strength is also higher than that of 20CrNi steel	It is often used to manufacture gears in engines and transmission systems of small and medium-sized cars and tractors; It can also replace the manufacturing requirements of 12CrNi3 steel Carburized parts and cyanided parts with high core performance, such as the jaw and cone body of the cone bit used in petroleum drilling and metallurgical open-pit mines
40CrNiMoA	It has high strength, high toughness and good hardenability. When it is hardened to semi-martensitic hardness (HRC45), the critical hardenability diameter of water quenching is ¢ ≥ 100mm, and the critical hardenability diameter of oil quenching is ¢ ≥ 75mm; When hardening to 90% martensite, the critical diameter of water quenching is ≯ 80-90mm, and the critical diameter of oil quenching is ¢ 55-66mm. This steel has stability against overheating, but it has high self-point sensitivity, temper brittleness, and poor weldability. It needs to be preheated at high temperature before welding, and stress relief treatment after welding	It is used after quenching and tempering to make important parts requiring good plasticity, high strength and large size, such as shafts with high load in heavy machinery Class II, turbine shaft, blade, high-load transmission parts, fasteners, crankshaft, gear, etc. with diameter greater than 250mm; It can also be used for rotor shafts and blades with operating temperature over 400 ° C. In addition, this steel can also be used to make special properties after nitriding Important parts required
