How about 51CrV4 spring steel properties

51CrV4 steel is high quality spring steel. 51CrV4 spring steel has high proportional limit and strength, high fatigue, good plasticity and toughness, and good tempering stability. Besides, other 51CrV4 spring steel properties are also recognized, for example, good machinability. However, the cold working plasticity of 51CrV4 spring steel is poor.

51CrV4 spring steel properties chemical composition:

Grade C Si Max Mn P Max S Max Cr V
51CrV4 0.47-0.55 0.4 0.7-1.1 0.025 0.025 0.9-1.2 0.10-0.25

51CrV4 spring steel properties - 51CrV4 steel plate mechanical property:

Grade Yield Strength(MPa) Tensile Strength(MPa) % Elongation min
51CrV4 900 1100-1300 12

Based on above 51CrV4 spring steel properties and its features, 51CrV4 spring steel is suitable for manufacturing all kinds of important springs with high stress, and the service temperature is not more than 400℃.
