Product Description: Steel Round Bar S156
S156 steel round bar is a high-quality tool steel designed for manufacturing cutting and forming tools. The material is characterized by high hardness, good wear resistance, and stable properties after heat treatment.
General Technical Characteristics
S156 steel provides an optimal balance of strength and hardness, making it effective in high-wear applications. After quenching and tempering, it achieves high resistance to mechanical loads and long service life.
Key properties:
- high hardness
- good wear resistance
- structural stability
- moderate impact toughness
Chemical Composition
The composition may vary depending on the manufacturer, but typically includes:
- Carbon (C): approx. 0.5–0.7%
- Chromium (Cr): 1.0–1.5%
- Manganese (Mn) and Silicon (Si): in moderate amounts
- Possible additions of Molybdenum (Mo) or Vanadium (V)
Alloying improves hardness and wear resistance.
Mechanical Properties
After heat treatment, the steel typically demonstrates:
- hardness: up to 55–60 HRC
- high wear resistance
- resistance to deformation
- sufficient strength under working loads
