- C45
| Element | Content (%) |
|---|---|
| C (Carbon) | 0.42 – 0.50 |
| Mn (Manganese) | 0.50 – 0.80 |
| Si (Silicon) | 0.15 – 0.35 |

Grade Brief
C45 is a medium carbon, non-alloy steel grade with approximately 0.45% carbon content. It offers good strength, hardness, and machinability. The material can be heat-treated (quenched and tempered) to enhance mechanical properties, making it suitable for parts requiring moderate tensile strength and wear resistance.
Key Characteristics
- Strength & Hardness: Good strength, moderate hardness, can be increased with quenching + tempering.
- Machinability: Good machinability in normalized or annealed condition.
- Weldability: Weldable with proper precautions (preheating & post-weld heat treatment recommended).
- Wear Resistance: Suitable for moderate wear applications.

Mechanical Properties of Steel
| Property | Value (Typical) |
|---|---|
| Tensile Strength (MPa) | 570 – 700 |
| Yield Strength (MPa) | ≥ 355 |
| Elongation (%) | ≥ 16 |
| Hardness (HB, Brinell) | 170 – 210 |
| Impact Strength (ISO-V) | ≥ 35 J |
Heat Treatment & Processes
| Process | Temperature (°C) | Cooling Medium | Notes |
|---|---|---|---|
| Annealing | 650 – 700 | Furnace | Refines grain, softens steel |
| Normalizing | 840 – 880 | Air | Improves machinability & toughness |
| Hardening (Quench) | 820 – 860 | Water/Oil | Achieves high hardness |
| Tempering | 540 – 680 | Air | Adjusts hardness & toughness |
Application
Shafts, gears, axles, crankshafts, Bolts, studs, connecting rods, Machinery parts, automotive components, Forged, parts requiring medium strength
Conclusion
C45 medium carbon steel is an all-purpose engineering material that is a combination of strength, hardness, and good machinability. It provides good wear resistance, toughness, mixed with proper heat treatment, which has made it perfect in shafts, gears, axles, crankshafts, and general parts of machinery. It is highly adaptable and available in both forged and machined versions, and as such has found extensive industrial applications in the automotive, mechanical, and structural industries.
