The longevity of hard chrome plating varies depending on the working environment and how thick the chrome is applied. But with the increased durability, a chromed surface will last much longer.
Electro-deposited chrome is extremely hard, typically 66-70 on the Rockwell “C” scale which is used to determine the indentation hardness of a material. In comparison, hardened knife steels typically measure 58-62 HRC.
Hard chrome has excellent corrosion resistance but it plates in a micro-crack structure so it will rust over extended periods of time in wet environments.
Any ferrous and most non-ferrous metals can be hard chrome plated, except for magnesium and titanium which typically require an underlay of zinc, copper or nickel. Some alloys of aluminum can be hard chrome plated directly, while some require an undercoat of copper or nickel. Common materials we plate are: steel, cast iron, stainless steel, bronza, brass and copper.
No. Although the processes are similar, they serve different functions. Hard chrome is widely used in industrial applications for increased wear and corrosion resistance, reduced friction and lubricant retention. Decorative chrome is a much thinner layer of chromium mainly for aesthetic appeal.
Hard chrome plating is an electrolytic method of depositing chrome on a substrate to improve corrosion and wear resistance, reduce friction and extend the life of parts used in extreme working conditions.
The cost can vary based on several factors such as part diameter, length, complexity and existing part condition. A quote will provided prior to commencing any work.
A typical delivery is 2-3 days from go-ahead, pending no major damage. To speed up the process, a quote can be provided over the phone or email.
