Is 50CrVa steel and 51CrV4 steel the same material?

50CrVa steel and 51CrV4 steel are named by different standards, 51CrV4 named according to German standard EN , 50CrVa is according to the Chinese standard GB/T . But materials are basically same.

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 &#;.

Scopes

1. is used as a tempering and spring steel for highly wear-resistant and through-hardening components. Especially in areas of automotive engineering and general mechanical engineering.

With us you can buy this material in an annealed design, so that after machining each component can be hardened individually.

In this case, tensile strengths of 800- N / mm² can be achieved - depending on the cross section - which makes the components harder than for example the usual engineering steel 1..

A small amount of silicon is added to obtain a corresponding elasticity at a high hardness at the same time.

1. is popularly known as AISI &#;&#;&#;&#;&#;.
 

Areas of application: 51CrV4 is used for a variety of parts, which should primarily have good toughness. The main industry for this material is the automotive industry, but also the machine and gear construction uses this material, if high-strength parts are needed.

Areas of use: the material 1. is most commonly used for camshafts, racks and pinions. In addition, from this material can be used for quality wrenches, cradles and scissors.
