Frequently Asked Questions
Common questions about our hard chrome plated rods.
What is a hard chrome plated rod?
A hard chrome plated rod is a precision-ground steel rod (commonly EN8, CK45 or 42CrMo4) electroplated with a 20-40 micron layer of hard chromium. The coating provides high surface hardness, wear resistance and corrosion protection, making it the standard piston rod used in hydraulic and pneumatic cylinders.
Which material grades does Kamal Hydrotech use for chrome plated rods?
Kamal Hydrotech manufactures hard chrome plated rods in EN8, CK45 and 42CrMo4 for standard and high-strength applications, and EN31 where higher wear resistance is required. Material is selected based on the cylinder load, pressure and operating environment.
What chrome thickness and tolerance are available?
Standard hard chrome layer thickness is 20-40 microns, with tolerance class h8 (f7 on request) and surface finish of Ra 0.2 micron. Diameters range from 8mm to 200mm in single-piece lengths up to 6 meters or customised to your drawing.
What are hard chrome plated rods used for?
They are used as piston rods and guide rods in hydraulic cylinders, pneumatic cylinders, construction equipment, machine tools, injection moulding machines and material handling systems - anywhere a wear-resistant, corrosion-resistant linear rod is needed.
Does Kamal Hydrotech supply chrome plated rods across India?
Yes. Kamal Hydrotech manufactures at MIDC Bhosari, Pune and supplies hard chrome plated rods pan-India, including Mumbai, Ahmedabad, Bengaluru, Chennai, Hyderabad and other industrial hubs, with export capability on request.
