What is the nickel content of stainless steel?

The nickel content of stainless steel 304 is about 10%, specifically between 8-10.5%.

304 stainless steel is widely used, thanks to its nickel-chromium content. 304 stainless steel has the following characteristics: corrosion resistance, oxidation resistance, easy processing, preventing product contamination, beautiful appearance, easy cleaning, low weight and high strength, good strength and toughness at cryogenic temperatures.

A nickel content (Ni) of 8% is resistant to neutral to weakly reducing environments such as cold dilute sulfuric acid. 18% chromium content (Cr) is resistant to neutral to moderately oxidizing solutions such as dilute nitric acid, moderately concentrated acetic acid and other organic acids.

Stainless Steel Construction Composition

The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, the maximum is not more than 1.2%, and the ωc (carbon content) of some steels is even lower than 0.03% (such as 00Cr12 ).

The main alloying element in stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.
