Mechanical Property of EN60Cr3 Spring Steel

EN60Cr3 spring steel has excellent mechanical properties, mainly including:

Performance Indicator Range
Tensile strength (σb, MPa) 1450~1750 (changes under different heat treatment conditions)
Yield strength (σ0.2, MPa) ≥1300
Elongation (δ5, %) ≥3 (or higher, depending on the heat treatment state)
Section shrinkage (ψ, %) ≥20
Hardness (HBW) hot rolling condition≤321; Cold drawing + heat treatment ≤321

In addition, 60Cr3 also has good impact toughness, usually 40~50J/cm².

Application Field

  1. Automobile industry

Suspension springs: Include front and rear suspension springs, which need to withstand various vibrations and shocks during vehicle driving.

Valve spring: Used in internal combustion engines to ensure that the valve can be opened and closed quickly and accurately.

Seat belt springs: Provide the necessary tension to ensure passenger safety in the event of a car crash.

  1. Industrial equipment

Die spring: In stamping and injection molds, it is used to hold the relative position of the parts of the mold.

Spring fixtures and fixture parts: used in machines and equipment to grip and position workpieces.

Safety valve springs: In pressure control systems, ensure that the equipment automatically releases pressure when it exceeds the safe pressure range.

  1. Agricultural machinery

Various springs on agricultural machinery, such as suspension springs and transmission system springs of harvesters, tractors, etc.

  1. Home appliances and office equipment

Shock absorbing springs in washing machines, refrigerators and other household appliances.

Spring components in office equipment such as printers and copiers.
