Product Overview

CK45 hard chrome plated piston rod, also known as a hard chrome bar. It is a precision engineered linear component where a CK45 carbon steel base material is electroplated with a thin, uniform layer of chromium. This specialized hard chrome plated piston rod offers exceptional surface properties, including extreme hardness (typically 66-70 HRC) and superior resistance to wear, abrasion, and corrosion.

Key Features

Wear & Corrosion Resistance: The hard chrome plating, with a minimum thickness of 20 microns and a surface hardness of 850-1150 HV, provides a shield against abrasion and corrosion, significantly extending the service life of your components.

Precision: With a mirror-smooth surface finish of Ra ≤ 0.2μm and tight diameter tolerances of ISO f7.

Superior Strength: Made from CK45 medium-carbon steel (equivalent to SAE1045), our hard chrome plated piston rods offer an optimal balance of strength and toughness, with a tensile strength of ≥610 N/mm² and yield strength of ≥355 N/mm².

Rigorous Quality Assurance: Every hard chrome plated piston rod is backed by ISO 9001 certified processes and undergoes strict testing, including salt spray tests per ASTM B117 for up to 72 hours.

FAQ

Q1: What is CK45 steel, and why is it used for this hard chrome plated piston rod?

A1: CK45 is a medium carbon steel with good strength, toughness, and machinability. Hard chrome plated piston rod provides an excellent, cost-effective base material that, when combined with hard chrome plating, creates a high-performance hard chrome plated piston rod.

Q2: How does the hard chrome plating improve a piston rod's performance?

A2: The hard chrome plating dramatically increases surface hardness for wear resistance, adds a corrosion-resistant barrier, and provides a smooth, low-friction finish. This trio of benefits is crucial for the longevity and reliability of a hard chrome bar in cylinder applications.

Q3: Can I request a specific hardness or chrome thickness for my custom order?

A3: Absolutely. Customization is our strength. We can tailor the hardness (e.g., HRC 50+) and chrome plating thickness on the hard chrome plated piston rod to meet your specific operational demands and environmental conditions.
