Materials of Die springs

​

1. 65Mn

​ The strength is relatively low, with a certain degree of toughness and plasticity, and the elastic coefficient is equivalent to that of alloy spring steel. But the hardenability is poor, mainly used for smaller size springs, injection mold springs.

Tensile Strength ≥735MPa

Yield Strength ≥430MPa

Elongation δ10 (%):14~21.5

Application: Can be competent for general injection molds, low price is its core competitiveness

2. 55Si2Mn

The 55Si2Mn spring steel has high strength, good elastic limit, high yield ratio, good toughness after heat treatment, and higher hardenability than 65Mn steel. It is suitable for the manufacture of flat springs with medium loads such as railway vehicles, automobiles, and tractors, and spiral springs with a diameter of less than 25mm. Cushion springs and cylinder safety valves are important springs that work under high stress, and can also be used as heat-resistant springs below 250°C.

Tensile Strength ≥1274MPa

Yield Strength ≥1176MPa

Elongation δ10 (%) ≥ 6%

Application: Can be competent for all the injection molds and punching dies, anti-deformation ability is its core competitiveness

3. 50CrVA

The 50CrVa is a high-grade spring steel, has higher toughness, strength and elastic limit, fatigue strength, lower elastic modulus, higher yield ratio and hardenability, and good impact toughness; suitable for manufacturing large cross-section high-load springs and valve springs and piston springs whose working temperature is not higher than 300℃;

Tensile Strength ≥1274MPa

Yield Strength ≥1127MPa

Elongation δ5 (%) ≥10%

Application: Can be competent for all the injection molds and punching dies, especially for high temperature injection molds and large punching dies, temperature resistance ability and high-loading are its core competitiveness
