Product Introduction

Material EN 10083-3 51CrV4 belongs to German standard spring steel, the implementation standard: DIN 17221-88

51CrMoV4 has excellent tensile strength, elastic limit and fatigue strength, and is often used as a spring steel for high-speed trains.

The chemical composition of 51CrMoV4 is shown below:

Spring Steel Flat Bar 6150 1.8159 DIN 51CrV4

51CrV4 Features and Applications:

51CrV4(1.8159) has good mechanical properties and process properties, high hardenability, adding vanadium to refine the grain of steel, reduce overheating sensitivity, improve strength and toughness, with high fatigue strength, yield ratio is also high, but poor weldability, cold deformation plasticity is low.

Is a higher level spring, used as a large cross-section of high load important spring and operating temperature. 300 ℃ valve spring, piston spring, safety valve spring.

51CrV4 Mechanical properties:

Tensile strength σb (MPa) : ≥1274(130)

Yield strength σs (MPa) : ≥1127(115)

Elongation δ5 (%) : ≥10

Section shrinkage ratio ψ (%) : ≥40

Hardness: hot rolling,≤321HB; Cold drawing + heat treatment,≤321HB

51CrV4 Heat treatment specification:

Quenching 850℃±20℃, oil cold; Tempering 500℃±50℃(for special needs, ±30℃).

51CrV4 Special steel density specification:

At present, in terms of the mold steel used at home and abroad, the density of the mold steel is generally about 7.85, and the mold steel is usually forged parts with a density of 8000-8400 kg/cubic meter. The proportion of alloying elements added to different die steels is not the same
