FAQ

FAQs

What’s the benefit of using a CK45 rod with HRC 25–32 surface hardness?

This hardness range offers a perfect compromise between wear resistance and ductility, making it ideal for dynamic motion and moderate pressure systems.
How does the Q+T treatment affect the CK45 rod's performance?

The Quenching and Tempering (Q+T) process improves the steel’s mechanical strength and stress resistance, enhancing the overall fatigue life of the hydraulic cylinder.
Is the CK45 rod suitable for outdoor or humid environments?

Yes. The chrome plating layer offers strong resistance against corrosion, but for highly corrosive environments, stainless-based options may be preferable.
What tolerance level does your CK45 Chrome Rod Q+T meet?

All rods are manufactured to ISO f7 tolerance, ensuring compatibility with common sealing systems and guiding components in hydraulic cylinders.
How does the cost of CK45 Q+T rods compare with alloy steel rods?

CK45 rods are generally more economical than alloy steel like 42CrMo4 or 20MnV6, while still delivering solid performance in medium-load applications.
