Nickel content of various stainless steel materials

There are many kinds of stainless steel used in the stainless steel market

201 stainless steel (available in general environment)

304 stainless steel (good corrosion resistance, high cost performance)

316L stainless steel (acid and corrosion resistant)

310S stainless steel (high temperature resistance, corrosion resistance)

321 stainless steel (high hardness)

The main thing you buy stainless steel is the nickel content. The higher the nickel content, the better the corrosion resistance. So when we buy stainless steel, most of us will ask about the nickel content. Today, let's talk about the nickel content of different materials.

The nickel content of 201 material is about 2-3.

The nickel content of 304 material is at the right of 7.85-9

The nickel content of 321 stainless steel and 304 stainless steel is the same 8-9

The nickel content of 316L stainless steel is about 12

The nickel content of 310S stainless steel is 20

The difference between 304 and 321 is that 321 contains Ti element, which enhances the hardness and high temperature resistance of stainless steel.
