Metal finishing Q&As since 1989


Salt Spray standard for Satin Nickel


I am Director of Operations for a furniture manufacturer in Southern California. I was interested in acquiring information on the industry standard for salt spray testing on nickel plated products. We produce furniture made from metals with satin nickel finish, and would like to conduct salt spray testing for corrosion. Our objective is to obtain information on what is an acceptable standard in the industry and work with our vendors on surpassing such standards. I would appreciate any feedback on this subject.

Hello Cesar,

I worked on technical specification for satin nickel (matte nickel) plated onto furniture.

In my opinion, the salt spray test (ISO 9227) is right to determine the protection against base material corrosion in other terms to determine the right type and thickness layer.

But, the salt spray test is a technical test, it is not made to give results concerning aesthetic deterioration.

As Nicolas pointed out salt spray is a technical test. It will tell you how many hours of the test the part (or generally a coupon) will withstand until a predetermined percentage of corrosion on predetermined significant surfaces. What this means is that salt spray testing has no direct relationship to real world corrosion other than to presume (not always correctly) that longer salt spray resistance will equal a more durable part.

Satin nickel finishes are a variable. Some finishes use a satin nickel which contains a suspended material. Other satin nickel is performed by varying operating parameters of bright nickel chemistry. Still other satin nickel is satined by preplate or post plate polishing/brushing operations.

In summation, determine what you are trying to achieve, write a specification or find an applicable spec for same then specify a test.

(I have worked with manufacturers of plated metal furniture for 25 years and have rarely found the finish corrosion tested (except for lacquers), instead the plating thickness is specified and its application is estimated by the time and current of plating. It may then be tested for thickness by destructive or non destructive means on sample parts).

I want to know how many hours in salt spray test, should be resist a satin nickel plating.
May be Gene Packman-Great Neck NY in accordance with his experience, tell us this question.
We use some parts with 10-15 microns thickness.
I would appreciate your answer
