Product Description: 60S2A / 60Si2Mn Sheet Steel
60S2A sheet steel (international equivalent 60Si2Mn) is a low-alloy spring steel with elevated silicon and carbon content. It is known for its high strength, elasticity, and resistance to cyclic loading, making it suitable for manufacturing critical components and assemblies subjected to repeated stress.
General Technical Characteristics
60S2A steel is designed for applications requiring a combination of high strength and the ability to withstand variable loads. After heat treatment, the material achieves increased hardness and wear resistance.
Key properties:
- high tensile strength
- excellent elasticity
- good hardenability
- resistance to fatigue loading
Chemical Composition
The balanced chemical composition ensures stable performance characteristics:
- Carbon (C): 0.56–0.64%
- Silicon (Si): 1.5–2.0%
- Manganese (Mn): 0.6–0.9%
- Sulfur (S) and Phosphorus (P): minimal content
Silicon improves elastic properties, while manganese enhances strength and hardenability.
