Among alloy steels, the composition of alloy steel plate 51CrV4 is notable for including vanadium (V) and containing a comparatively high amount of chromium (Cr). Vanadium has a strong hardening effect on alloy steel plate 51CrV4. But this effect is particularly sensitive to the type of tempering. Chromium is used to improve corrosion resistance of alloy steel plate 51CrV4 and most mechanical properties (particularly at higher temperatures).

Alloy steel plate 51CrV4 is high strength steel suitable for quenched and tempered springs. Alloy steel plate 51CrV4 process high hardenability. The vanadium refines grain, reduces thermal sensitivity, improves alloy steel plate 51CrV4 strength and toughness. Alloy steel plate 51CrV4 has high fatigue strength, high yield ratio, but poor weldability and cold deformation due to low plasticity.
