We manufacture forging ingots, billets, and blooms in carbon steel specifically for C60, designed for high strength and high hardness engineering applications where excellent wear resistance and edge retention are required.
C60 is a high carbon, unalloyed engineering steel known for its very high hardness and strength after heat treatment. Due to its elevated carbon content, C60 offers superior wear resistance and is ideal for components subjected to abrasion, friction, and heavy service conditions. This grade is widely used in tools, springs, and heavy-duty engineering applications.
| Element | Content (%) | Function / effect |
| Carbon (c) | 0.57 - 0.65 | Provides very high hardness, strength, and wear resistance |
| Manganese (Mn) | 0.50 - 0.80 | Improves hardenability and toughness |
| Sulfur (s) | 0.045 max | Controlled to maintain toughness and machinability |
| Phosphorus (p) | 0.045 max | Limited to prevent brittleness |
| Silicon (si) | 0.15 - 0.35 | Increases strength and acts as deoxidizer |
| Chromium (cr) | Nil | Not intentionally added |
| Nickel (ni) | Nil | Not present |
| Molybdenum (mo) | Nil | Not present |
| Other elements | — | No significant alloying additions |
(Properties may vary depending on section size and heat treatment conditions)
C60 is the preferred choice when very high hardness, wear resistance, and edge retention are required. Its simple chemistry, excellent hardenability, and cost-effectiveness make it ideal for tools, springs, and heavy-duty engineering components.
