Brass plating on stainless steel?



A discussion started in 2008 but continuing through 2018

August 13, 2008

Q. I am engaged in architectural hardware business. One of my customers is asking for stainless steel material in satin brass and antique brass finish.

What is the best method for achieving these finishes on stainless steel base material? I would appreciate any references to such finish processes. How does such a product compare with the original versions in 'solid brass' material?

Thanks for your attention!

A. Dear sir,
If you want to do the brass plating on stainless steel first you have to do nickel strike plating then you go for the brass plating. Nickel strike bath contains nickel chloride and hydrochloric acid. generally nickel strike plating takes 2-5 min.

Q. Dear Sir

Thanks very much for your reply! Is it possible to achieve a very similar colour to brass? Most of the samples I have seen looked very 'pale' and not very valuable.

Thanks!

A. The nickel strike, commonly referred to as a Woods Nickel Strike, is used as a base for subsequent plating. If you are trying to do a bright brass flash a Watts type nickel underplate is necessary. If you desire a "heavy brass" then you can plate that over the Woods Strike although I would personally prefer a short Watts Nickel plate.

A. Sir,
If you want good brass finishing, after strike nickel plating you have to bright nickel plate, then go for brass plating -- then it appears good. Try it, good luck

Thanks!

Electrocoating: a Guidebook for Finishers

Hi Ashwini. Stainless steel can certainly be brass plated per above descriptions and lacquered. To reiterate, you need to start with Wood's nickel to get adhesion on stainless steel. Then you can either do just brass plating if you don't need shine, or you can do bright nickel plating followed by brass plating if you want a reflective shine. However, electrocoating the nickel plating with a lacquer with a brass tint might be easier and cheaper. Good luck.

A. Hi Jayanti. I'm not sure that I understand your question, but stainless steel can be nickel plated then gold plated. Alternately, titanium nitride is gold colored, and is applied to stainless steel by PVD processes.

Q. Hello. Can I electroplate brass onto Stainless steel than put on a clear protective PVD coating? Is this the most durable finishing? What size restrictions would be for the PVD coating. Thanks.

A. Hi Mike it's possible that shops have different size vacuum chambers, so I don't know the exact limits, although probably not very big for fabricated parts, although I've heard of titanium nitride plated stainless steel sheets up to about 4' x 10'.

But I would not do brass plating and follow it with a PVD clearcoat. I'd just go directly for a PVD coating of titanium nitride or other material which delivers the tone you are looking for. You might google "titanium nitride stainless sheet"
