C45 Chemical Composition
| Element | Range (per standard) |
|---|---|
| Carbon (C) | 0.42 – 0.50 % |
| Manganese (Mn) | 0.50 – 0.80 % |
| Silicon (Si) | 0.40 % max |
| Sulphur (S) | 0.045 % max |
| Phosphorus (P) | 0.045 % max |
Reference ranges vary by standard revision and exact designation. Confirm the purchase specification and use the Mill Test Certificate for the supplied heat.
C45 Properties & Condition
| Property | Typical Value |
|---|---|
| Tensile Strength | 570 – 700 MPa |
| Typical Condition | Normalised |
| Machinability | Good in normalised condition |
| Weldability | Weldable with preheat |
Mechanical properties depend on heat-treatment condition and section size. Confirm the required values against the governing order specification before purchase.
