4 Advice to Choose a steel grade 50crv4 vs 51crv4

Variety of steel

Goto HEGONG SPRING to know more.

Spring steel is a name given to a wide range of steels[1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting.

Grades

Many grades of steel can be hardened and tempered to increase elasticity and resist deformation; however, some steels are inherently more elastic than others:

50CrV4 steel and 51CrV4 steel are produced by different European standards, and the materials are basically the same. The main difference between 50CrV4 steel and 51CrV4 steel is the carbon content:
Carbon content of 50CrV4 steel: 0.46-0.54
Carbon content of 51CrV4 steel: 0.47-0.55

50CrV4 steel belongs to alloy spring steel. 50CrV4 steel is German standard steel grade, which corresponds to 50CrVA in China.

51CrV4 steel is a kind of higher-level spring steel. 51CrV4 steel has good mechanical and technological properties, high hardenability, high fatigue strength and high yield ratio. 51CrV4 steel is used as the important spring of high load with large cross-section and valve spring, piston spring and safety valve spring with working temperature < 300 '.
