Product Description

CK45 Chrome Plated Rod Induction and Hardened (HRC 25–32) is manufactured from high-grade medium carbon steel and treated by induction hardening. This process hardens the surface to HRC 25–32 while keeping the core tough and ductile. A layer of hard chrome plating (typically 20–30μm thick) is then applied for excellent corrosion and wear resistance.

This hard chrome plated rod is built to perform under high pressure, side loads, and harsh environments. It is commonly used as a cylinder rod in construction machinery, hydraulic presses, and industrial equipment where strength and surface durability are critical.

Offshore and marine hydraulics
Factory automation and industrial robots

This chrome bar is designed to withstand friction, load, and corrosion in challenging environments without compromising precision.

FAQ

FAQs

What is the main advantage of induction hardened CK45 chrome plated rods?

They offer a tough core with a hardened surface (HRC 25–32), giving excellent resistance to wear and bending stress—ideal for high-load cylinder applications.
How is it different from a standard hard chrome plated rod?

While both have chrome coating, the induction hardened version has improved surface hardness and better fatigue resistance under dynamic loads.
Can this rod be used in marine or corrosive environments?

Yes, the chrome layer provides excellent rust protection, but for extended marine use, pairing with proper sealing and maintenance is recommended.
Is CK45 chrome bar weldable?

Yes, CK45 can be welded, but care must be taken due to the hardened surface. Preheating and post-weld tempering may be required.
What’s the typical lead time and delivery for these cylinder rods?

Standard sizes are often in stock. Custom lengths or special tolerances typically require 7–15 business days depending on volume.
