C1026
C1026 is a medium-carbon steel grade classified under ASTM A29/A29M standards, optimized for cold forging and machining.
Descriptions
1. Chemical Composition
The chemical compositions of AISI 1008 and 1010 (per ASTM A29/A29M and SAE J403 standards) are:
| Element | Composition (%) |
| Carbon (C) | 0.22-0.28 |
| Manganese (Mn) | 0.60-0.90 |
| Phosphorus (P) | ≤0.040 |
| Sulfur (S) | ≤0.050 |
| Iron (Fe) | Balance(~98.7%) |
2. Mechanical Properties
Typical mechanical properties for C1026 forgings (cold-finished or annealed condition):
| Property | Cold-Forged | Annealed |
| Tensile Strength | 540-690 MPa(78-100 ksi) | 430-550 MPa(62-80 ksi) |
| Yield Strength(0.2%) | 480-620 MPa(70-90 ksi) | 340-450 MPa(49-65 ksi) |
| Elongation (50mm) | 10-15% | 20-30% |
| Hardness (Brinell) | 160-210HB | 120-150HB |
| Modulus of Elasticity | 200 GPa (29,000 ksi) | 200 GPa (29,000 ksi) |
| Density | 7.87 g/cm3 | 7.87 g/cm3 |
3. Key Advantages
Cold Forgeability: Excellent for high-speed cold forming without cracking.
Machinability: Good for drilling, threading, and milling in annealed condition.
Cost Efficiency: Ideal for mass production of small to medium-sized parts.
Surface Quality: Smooth finish suitable for plating (e.g., zinc, nickel).
4. Limitations
Limited Weldability: Prone to cracking if welded without pre/post-heat treatment.
Corrosion Sensitivity: Requires coatings for outdoor or corrosive environments.
Not for High-Temperature Use: Loses strength above 300°C (570°F).
