S45C Hard Chrome Plated Steel Bars are widely used across hydraulic systems and industrial equipment because they offer a well-balanced combination of mechanical strength and surface performance. By combining medium carbon steel with a hard chrome-plated layer, these bars deliver reliable performance in applications that require durability, smooth motion, and stable sealing behavior.
Highlights
- High-strength S45C core for load-bearing applications
- Hard chrome hardness of HV850 minimum
- Ra 0.2 μm maximum for smooth, low-friction motion
- Strong corrosion resistance for demanding environments
- Multiple ISO tolerances for precision fitting
- Straightness of 0.3 mm/m for stable linear motion
- Multiple sizes and custom lengths available
