Custom Chrome-Silicon Springs: Optimization for Extreme Conditions

Technical Superiority: Chrome-Silicon Core Unifies the Limits of Durability and Performance

Chrome-Silicon has high tensile strength and resilience at higher temperatures, making Chrome-Silicon steel suitable for springs and wire forms that must withstand shock loads, high stress and temperature environments.

Technical Specification: Chrome-Silicon
Nominal Composition C: 0.51 – 0.59 Cr: 0.60 – 0.80 Si: 1.20 – 1.60
Density: 0.284 lb./in3
Elasticity modulus (E): 30 x 106 psi
Shear modulus (G): 11.5 x 106 ksi
Coefficient of expansion:
Electrical Resistance: 32.3 µΩ.in
Thermal Conductivity: 108 Btu/(hr/ft2/in/°F)
Minimum Size: 0.016 in (0.406 mm)
Maximum Temperature: 246oC (475oF)
Its resilience against high impact, shock loading and high temperature makes it a suitable material for valve springs in performance vehicles such as racing cars and recoil springs of firearms.
