| Product introduction | ||||||||||||||||
| Both 50CrV and 50CrVA belong to the national standard spring steel and are made of the same material. The only difference is that the standard year is different. | ||||||||||||||||
| Properties of 50CrV alloy steel: | 1. Good mechanical properties and technological properties, 2. High hardenability, 3. Adding vanadium can refine the grain of steel, reduce overheating sensitivity and improve strength and toughness. 4. It has high fatigue strength and high yield ratio. 5. Poor weldability and low plasticity due to cold deformation. |
|||||||||||||||
| 50CrV alloy steel uses: | Used as high-load important spring with large cross section and valve spring, piston spring and safety valve spring with working temperature < 300ºC. | |||||||||||||||
