| Product introduction | ||||||||||||||||
| 40Cr steel is a low-alloy structural steel independently developed in China. | ||||||||||||||||
| Properties of 40Cr alloy steel: | 1. the performance of 45cr is higher than 30Mn2, 2. It has high strength and wear resistance, high hardenability and moderate cold deformation plasticity. 3. The machinability is good, the weldability is acceptable, and the toughness of steel decreases less during heat treatment. 4. It can still maintain high toughness when cooled by water. 5. It has overheating sensitivity, white spot sensitivity and temper brittleness tendency, and is mostly used after quenching and tempering, and can also be used in normalized or hot rolling supply state. |
|||||||||||||||
| 40Cr alloy steel uses: | As a special steel for mining support equipment-hydraulic support column, it has excellent toughness and mechanical properties. 27SiMn steel is mainly used in quenched and tempered state, and is used to manufacture hot stamping parts with high strength, toughness and good wear resistance. It is widely used to manufacture hydraulic props, high-pressure boilers and other equipment, and can also be used in normalized or hot-rolled state, such as crawler pins of tractors. | |||||||||||||||
