Composition and properties
Structural spring steel 60C2A differs from its basic domestic analogue — steel 60C2 by more stringent tolerances on the percentage of all chemical elements, as follows:
| Element | Carbon | Silicon | Manganese | Nickel | Chrome | Copper |
|---|---|---|---|---|---|---|
| Percentage content | 0,58…0,63 | 1,6…2,0 | 0,6…0,9 | Up to 0.25 | Up to 0.3 | 0.3 Up to 0.2 |
The percentage of metallurgical impurities in steel 60S2A — phosphorus and sulfur is limited to 0.025% for each of these elements.
The nearest analogues of this steel are 60MnSiCr4, melted in accordance with DIN 17221 in Germany, and 1.2826, which is considered as tool steel in the USA. Whereas 60MnSiCr4 steel differs from the domestic 60C2A steel only in having higher chromium content of up to 0.4% and, conversely, lower manganese content of up to 1%, 1.2826 steel has more noticeable variations in its chemical composition (see table):
| Element | Carbon | Silicon | Manganese | Nickel | Chrome | Copper |
|---|---|---|---|---|---|---|
| Percentage content | 0,58…0,65 | 0,8…1,0 | 0,8…1,2 | - | 0,20…0,40 | - |
The physical-mechanical characteristics of the steels under consideration after annealing should correspond to the following numerical values:
- Ultimate tensile strength, MPa — 293;
- ultimate ductility, MPa — 225;
- Tensile strength, kJ/m2 — 22…23;
- Relative elongation, % — 13;
- Relative narrowing of cross-sectional area, % — 11;
- Brinell hardness — 215 NV.
Application of .
The steels in the range of volumetric rolled products — rounds, wires, bars — are used in the manufacture of heavy-duty springs, torsion-type shafts, collets of machine tools, etc. The wire is used to produce spring rings, Grover washers and other products that require increased resistance to dynamic and shock loads.
Rolled 60C2A, 60MnSiCr4 and 1.2826 steels are used as billets for hot forging, after which the structural heterogeneity of the material is reduced. Subsequently, from the resulting semi-finished products are made irrelevant parts of cold stamping equipment.
U.S. sourcing overview
60S2A is a silicon-manganese spring-steel designation used in regional technical documentation; 60MnSiCr4 appears in European specifications for a related alloy family. Cross-reference information is useful for sourcing, but the purchase requirement must retain the exact grade, standard and heat-treatment condition.
Product forms and sourcing
Supply can be reviewed for round bar, rod, wire, cut lengths and blanks, depending on diameter, condition and quantity. State coil or straight-length form, diameter tolerance, straightness, surface condition, decarburization limits, machining allowance and any heat-treatment requirement.
Evek LLC reviews each requirement against the requested grade, specification, form, dimensions and quantity. Availability, origin, production route, minimum quantity and certification are confirmed during quotation; website text is not a stock or compliance guarantee.
Specification and substitution
Similar spring-steel designations may have different chemistry ranges, cleanliness limits, hardenability, heat-treatment response and test requirements. Do not authorize a substitute from nominal similarity alone; confirm the drawing, target properties and governing specification.
The purchaser remains responsible for material selection, design approval and confirmation that the specified material is suitable for the finished component, manufacturing process and service environment.
