The chemical composition range of 52100 steel is shown in the following table：
| Element | Content Range |
| Carbon (C) | 0.93% – 1.10% |
| Chromium (Cr) | 1.30% – 1.60% |
| Silicon (Si) | 0.15% – 0.35% |
| Manganese (Mn) | 0.25% – 0.45% |
| Phosphorus (P) | ≤ 0.025% |
| Sulfur (S) | ≤ 0.025% |
The applications of 52100 steel are as follows:
- Bearing Industry: It is widely used in the manufacturing of ball bearings and roller bearings. The high hardness and excellent wear resistance of 52100 steel can ensure the smooth operation and long service life of bearings under high pressure and high-speed rotation conditions.
- Tool and Die Manufacturing: This steel is suitable for making precision cutting tools such as lathe tools and milling cutters. Its high hardness enables the tools to maintain a sharp cutting edge, making it ideal for machining hard materials. Additionally, it can be used in die-making, especially for small-sized, high-precision dies where high hardness and good dimensional stability are required.
- Automotive Sector: In the automotive industry, 52100 steel is applied to critical components like shafts and gears in the transmission system. The strength and wear resistance of the steel help reduce wear during power transmission, thereby enhancing the overall performance and durability of vehicles.
- Mining Equipment: It is used to fabricate wear-resistant parts of mining machinery, such as crusher liners, excavator buckets, and ball mill liners. These parts need to withstand severe abrasion from ores and rocks, and 52100 steel can provide the necessary durability.
