SCM420 wire is a high-quality alloy structural steel wire product with many excellent properties. The wire has high tensile strength and a certain yield strength, and can withstand large stresses. At the same time, the elongation and cross-sectional shrinkage indicate that it has good toughness and can effectively resist impact and vibration. The hardness is in a suitable range, which is both wear-resistant and easy to process. In addition, it is easy to deform during cold processing, and can be cold drawn, cold headed and other operations to manufacture parts of various shapes to meet the diverse needs of users.

Chemical element content (%)

Specification：1.00~42.00mm

Application: Mainly used in the manufacture of engines, transmissions, drive shafts, gears, fasteners, high-pressure pipes, carburized parts, shafts, bearings, structural parts, etc.; widely used in automobiles, machinery manufacturing, aerospace, petrochemicals and other fields.

Heat treatment specifications:
The quenching temperature is generally 880℃, water cooling or oil cooling;
The tempering temperature is 500℃, water cooling or oil cooling.

Physical properties:
-- The density is 7.85g/cm³, which is a high-density steel, which makes the wire have higher quality and stability.
-- The melting point is about 1426°C, with high heat resistance, and can maintain good mechanical properties and stability in high temperature environment.
-- The coefficient of thermal expansion is 11.2x10⁻⁶/°C (room temperature to 100°C) and the thermal conductivity is 46.6W/(m・K). These physical properties are important for the use of steel in different temperature environments.
