60Si2CrA wire is an important spring steel wire. The specific chemical composition makes it a perfect combination of strength and toughness. It has high strength and good toughness, which enables it to withstand large stress and load, and can effectively prevent brittle fracture of wire during use, improving the reliability and service life of the product; it also has excellent elasticity and elastic recovery performance, and can quickly return to its original state after deformation, and is not prone to fatigue damage, ensuring long-term stable performance, and contributing indispensable power to the world's industrial development and machinery manufacturing.

Chemical element content (%)

Specification：1.00~42.00mm

Application areas: Suitable for manufacturing springs that withstand high stress and working temperature below 300-350℃, chisels, needles, shafts, gears, etc. for fitters; widely used in automobiles, machinery and other fields.

Processing technology:

-Heat treatment: Usually a heat treatment process of quenching and medium-temperature tempering is used. The quenching temperature is generally 870℃±20℃, oil-cooled quenching; the tempering temperature is 420℃±50℃ (±30℃ when special needs are needed).

-Cold processing: The cold processing performance is good, and cold drawing, cold rolling and other processing processes can be carried out to obtain the required size and shape.

Mechanical properties:

-Tensile strength: ≥1764MPa (180kgf/mm²).

-Yield strength: ≥1568MPa (160kgf/mm²).

-Elongation: ≥6%.

-Sectional shrinkage: ≥20%.

-Hardness 23: Under hot-rolled heating treatment, the hardness is ≤321HB; under cold-drawn heating treatment, the hardness is also ≤321HB.
