Is nickel-plated steel corrosion resistant?

Question

If nickel-plated steel is exposed to rain/moisture, will it be protected from rusting? And what's the difference between nickel-plated steel and stainless steel?

Answer 1

Nickel-Plated steels are designed to resist incidental contact or exposure to water or water based wash-down operations.

Correct procedure applies an electroless nickel plating to the component parts prior to assembly to insure complete coverage of all exposed carbon material.

Special attention is placed on after-plating processes to virtually remove the possibility of hydrogen embrittlement – a common occurrence in lesser quality steels.

-In metallurgy, stainless steel is defined as a steel alloy with a minimum of 11.5% chromium content by mass.[1] Stainless steel does not stain, corrode or rust as easily as ordinary steel (it "stains less"), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Common uses of stainless steel are cutlery and watch straps.

Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by forming more iron oxide. Stainless steels have sufficient amount of chromium present so that a passive film of chromium oxide forms which prevents further corrosion.

All alloy steels are not stainless steels.

So, nickle plated steel and stainless steels are different.

Answer 2

Yes.  Have you ever seen rust on a nickel?

Stainless steel is an alloying process with specific composition (varies depending upon what type of stainless it is) of alloying elements.  The elements are heated and composition througout is relatively constant if the steel is made correctly.  Nickel plated steel has carbon steel with solid nickel plated (either electrochemically or mechanically plated) on the surface.

Answer 3

There is no doubt that the nickel is corrosion resistant.

Here the important parameter is to consider what kind of steel we are using and what is the atmospheric conditions of the material at  end use.

Becs there are veriety of application and for that veriety of coating and plating methods are there.

Conditions like

parts which will exposed to corrosive atmosphere like see soar

and Chemical enviroinment etc.

there are kind of processes depending up on end use.

If is for Tank or Vessel - we have to go for Nickel cladding on steel P5 or P9.

If it is ornmental we can go for plating with electrolysis method or Metal Power or wire spray process.

There are so many sites available in the net now a day.

Good luck have a nice time

Answer 4

Yes depending on the quality and thickness of the nickel plate.  Stainless steel is a steel alloy containing chromium, nickel, and other metals.  Depending on the type of stainless steel it is inherently corrosion resistant.
