There are many advantages to using electroless nickel plating as an alternative to hard chrome.
Hard chrome is a common choice where the hardness and wear resistance of a component are important. The hardness of hard chrome is in the region of 800 – 1100 VHN.
The hard chrome deposit, however, is applied electrolytically. Metal coatings applied electrolytically generally create an uneven coating which may need post plating machining. The difference in coating uniformity between electrolytic and and electroless nickel plating is illustrated in the image below, and the same theory can be applied to hard chrome applied eloctrolytically and electroless nickel plating. Another disadvantage to hard chrome is that it tends to soften with heating.
Electroless nickel deposits form a perfectly uniform coating, unlike hard chrome. Although electroless nickel does not give the same level of hardness, the process of heat treatment can be used to harden it. Some electroless nickel deposits can be harder than 1000 VHN, making the hardness of electroless nickel plating comparable to that of hard chrome.
As well a electroless nickel plating, Electroless Nickel Plating Specialist also specialise in diffused nickel plating finishes, copper plating as a process, shotblasting and heat treatment.

As specialists in electroless nickel plating, Electroless Nickel Plating Specialist are passionate about promoting the advantages of the process over using other metals, such as stainless steel.
Stainless steel is very resistant to corrosion, and can therefore be used when the levels of hardness of the metal are important. But using electroless nickel plating as an alternative to stainless steel has many advantages. Mild steel or cast iron with an electroless nickel coating is a much more cost effective way of achieving high levels of hardness and corrosion resistance.
Stainless steel doesn’t corrode, rust or stain easily with water as ordinary steel would do, but despite its name, stainless steel is not actually fully stain proof. Stainless steel will in fact stain and even corrode in conditions where there are low levels of oxygen, high levels of salt or poor circulation.
As a specialist electroless nickel plating company in Chesterfield, Electroless Nickel Plating Specialist are experts in the plating industry. A question that is frequently asked by customers and potential customers alike is ‘Exactly how hard is electroless nickel plating?
Depending on the phosphorus content in the deposit, electroless nickel deposits have hardness values in the range of 450 – 750 VHN. As a rule, the higher the phosphorus content, the lower the deposited hardness of the electroless nickel.Mild steel with an electroless nickel coating has properties of hardness and corrosion resistance exceeding the benefits offered by stainless steel.
Increasing hardness of electroless nickel using heat treatment
An effective way of increasing the hardness of the electroless nickel coating is by using the process of heat treatment. Heat treatment can increase the hardness of electroless nickel coatings to in excess of 1000 VHN. This makes the nickel deposit hardness on par with hard chrome, with the added advantage of an even coating which will not require any machinery after plating.
The electroless nickel plating process is a cost effective solution to coating metals such as mild or stainless steel.
And despite the lower price, electroless nickel coatings still maintain a high level of quality.
Advantages of electroless nickel plating
The metal layer deposited by the electroless nickel plating process has an even thickness over all surfaces of the component, virtually regardless of its shape. This uniform coating is the perfect solution for critical high-end engineering items such as those used in the defense healthcare, automotive and aerospace industries.
How corrosion resistant is electroless nickel?
Electroless nickel is perfect for parts that are regularly exposed to harsh environments such as the marine, oil and gas and defense industries. Nickel plating is very resistant to corrosion and will therefore substantially extend the life of a component. Therefore it can reduce the cost of repair and replacement parts.
How hard is electroless nickel?
When electroless nickel plating is used in association with an appropriate heat treatment, it can be hardened up to 950vhn. Electroless nickel plating is therefore ideal in areas where friction and wear are issues.
Electroless Nickel Plating Specialist are leading specialists in the process of electroless nickel plating.
As a plating company established in 1978, we have developed a wide range of techniques and developed leading technology within the plating industry.
