We manufacture forging ingots, billets, and blooms in carbon steel specifically for SAE 1020, designed for low strength engineering applications where good ductility, weldability, and formability are required.
SAE 1020 is a low carbon, unalloyed steel with approximately 0.20% carbon content. It offers excellent machinability, high ductility, and good weldability, making it ideal for fabrication and components subjected to low to moderate mechanical loads.
| Element | Content (%) | Function / effect |
| Carbon (c) | 0.18 – 0.23 | Provides low to moderate strength and good ductility |
| Manganese (mn) | 0.30 – 0.60 | Improves toughness and hardenability |
| Phosphorus (p) | 0.040 max | Controlled to prevent brittleness |
| Sulphur (s) | 0.050 max | Improves machinability when controlled |
| Silicon (si) | 0.10 – 0.35 | Acts as deoxidizer and improves strength |
| Chromium (cr) | Nil | Not intentionally added |
| Nickel (ni) | Nil | Not present |
| Molybdenum (mo) | Nil | Not present |
| Other elements | — | No significant alloying additions |
SAE 1020 Is An Excellent Choice For Applications Requiring Moderate Strength, Good Machinability, And Case Hardening Capability. Its Versatility And Ease Of ProceSSing Make It Suitable For A Wide Range Of Engineering And Automotive Components.
