| Product introduction | ||||||||||||||||
| 50CrMo4 belongs to ultra-high strength alloy structural steel, | ||||||||||||||||
| Properties of 50CrMo alloy steel: | 1. It has high strength and toughness, 2. Good hardenability, 3. No obvious temper brittleness. 4. After quenching and tempering treatment, it has higher fatigue limit and multiple impact resistance. 5. Good low-temperature impact toughness, 6. High creep strength and durable strength at high temperature. |
|||||||||||||||
| 50CrMo alloy steel uses: | It can be used to manufacture large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, connecting rods and spring clips under great load, drill pipe joints and fishing tools in deep oil wells below 2000m, and can be used for dies of bending machines. | |||||||||||||||
