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
