S55C Induction Hardened Hard Chrome Plated Steel Bar
Model：S55C
Supplier： FU-LONG METAL INDUSTRIAL CO., LTD.
S55C is a higher-carbon medium-carbon steel that achieves superior surface hardness and excellent wear resistance through induction hardening. It provides high strength, fatigue resistance, and a stable hardened layer for long-term operation under demanding conditions. It is mainly used in heavy-duty hydraulic cylinders, construction machinery, injection molding machines, and high-wear application
Highlights
- High-strength S55C core for load-bearing applications
- Hard chrome hardness of HV850 minimum
- Ra 0.2µm 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
