Performance comparison of 201 stainless steel and 304 stainless steel

Stainless Steel Sheets

1, fatigue strength, 201 hardness is larger, toughness is not as 304, or 304 fatigue resistance is better.

2, 304 stainless steel plate quality is better, but the price is expensive, 201 is poor.
304 stainless steel is imported stainless steel plate,201 is domestic stainless steel plate.

3, 201 is high in manganese, the surface is very bright with dark light, high in manganese easy to rust.
304 contains more chromium and the surface is matte without rust. The two kinds are compared when put together.
The most important thing is that the corrosion resistance is different, the corrosion resistance of 201 is very poor, so the price is much cheaper. And because the nickel content of 201 is low, the price is lower than that of 304, so the corrosion resistance is not as good as that of 304.

4, stainless steel is not easy to rust because the formation of chrome-rich oxide on the surface of the steel body can protect the steel body,201 stainless steel material belongs to high manganese stainless steel than 304 stainless steel hardness high carbon low nickel.

5. The difference between 201 stainless steel plate and 304 stainless steel plate is the problem of nickel.
And the price of 304 is now more expensive, generally close to 50,000 a ton, but the words of 304 can at least ensure that in the use of the process will not rust.

6, the commonly used stainless steel plate is divided into 201 stainless steel plate and 304 stainless steel plate two models, the actual is the composition is different, 201 is composed of 17cr-4.5 ni-6mn-n, is the replacement of 301 stainless steel steel.
Magnetic after cold processing, used in railway vehicles.
Composed of 18Cr-9Ni, 304 is the most widely used stainless steel and heat resistant steel.
For food production equipment, xitong chemical equipment, nuclear energy and so on.
