Steel circle 35HGS / 35KhGS
Steel 35HGS (35KhGS) is a structural alloy steel distinguished by its high strength, wear resistance, and impact toughness. It is widely used in mechanical engineering, aviation, and the production of critical components.
Key Material Characteristics
- High strength and hardness – after heat treatment up to 30-40 HRC
- Excellent impact toughness – resistant to dynamic loads
- Good hardenability – uniform hardness distribution across the section
- Wear resistance – durability under friction conditions
- Dimensional stability – minimal deformation after processing
Applications
- Machine and mechanism parts – gears, shafts, axles
- Automotive industry – gearbox components, suspension elements
- Aerospace industry – structural load-bearing elements
- Hydraulic systems – rods, pistons
- Construction equipment – heavily loaded assemblies
Chemical Composition
| Element | Content, % |
|---|---|
| Carbon (C) | 0.32-0.40 |
| Silicon (Si) | 0.17-0.37 |
| Manganese (Mn) | 0.50-0.80 |
| Chromium (Cr) | 0.80-1.10 |
| Molybdenum (Mo) | 0.15-0.30 |
| Sulfur (S) | ≤0.025 |
| Phosphorus (P) | ≤0.025 |
The combination of chromium, manganese, and molybdenum provides excellent strength and wear resistance.
Mechanical Properties
- Yield strength: 900-1100 MPa
