Replace Stainless Steel with Electroless Nickel Plating for Large Parts

Electroless nickel is often used as a replacement for stainless steel on large parts.

Stainless steel is very expensive, and it is often difficult to find a source to cast large stainless steel components. A more cost effective and time saving solution is to make large parts out of cast iron and then electroless nickel plate them for corrosion resistance.

Electroless nickel is perfect for plating large machined parts that need to be resistant to corrosion.

Conventional electro-deposit such as hard chrome or electrolytic nickel need to be machined after plating to hold dimensional accuracy. This re-machining on large, electroplated parts can cost hundreds to thousands of pounds. With electroless nickel plating, the job is complete once you have plated the part.

Consider electroless nickel plating

When designing large parts, electroless nickel should be considered if hardness, corrosion resistance, and wear are a concern.

Electroless nickel properties and characteristics often give it a significant advantage over conventional materials and methods. The equipment and methods used at NiTEC mean that even the most difficult large part can be plated correctly and consistently.

As leading specialists in the electroless nickel plating field, we have the facilities to plate large components, unlike small firms.

Replacing Hard Chrome with Electroless Nickel Plating

A great feature of electroless nickel plating is its hardness. Hardness values for electroless nickel deposits are in the range of 450-750 VHN, depending on the phosphorous content of the deposit.

Another great feature of electroless nickel plating is wear resistance. It’s often assumed that hardness is synonymous with wear resistance, and depending upon the wear mechanism applied, this is true in some cases.

Hard chrome can be used when it’s important for the surface to be hard and wear resistant. The advantage of this is that it is very hard, in the region of 800-1100 VHN. The downside, however, is that as the deposit is applied electrolytically, the result is an uneven coating. This means the surface may need post plating machining.

With electroless nickel plating, the surface is guaranteed to be uniform. And although the hardness value isn’t as high as chrome, this can be overcome by using heat treatment.

Hard chrome tends to soften with heating, but all types of electroless nickel plating can be hardened by using heat treatment. In fact, with the right heat treatment, some electroless nickel deposits can be harder than 1000 VHN, making the hardness of electroless nickel plating comparible to that of hard chrome.

As well a electroless nickel plating, we also specialise in diffused nickel plating finishes, copper plating as a process, shotblasting and heat treatment.
