What Is The Difference Between Stainless Steel 304 And 201?
Dec 29, 2018

In the eyes of many consumers, there is almost no difference between 304 stainless steel and 201 stainless steel, which can hardly be distinguished by the naked eye. Here are some ways to distinguish between 304 and 201.

    1. Specifications: Commonly used stainless steel plates are divided into two models, 201 and 304. Actually, the composition is different, and the 304 quality is better, but the price is higher, and the difference is 201. 304 is imported stainless steel plate and 201 is domestic stainless steel plate.

    2, 201 composition of 17Cr-4.5Ni-6Mn-N, is a Ni steel grade, 301 steel alternative steel. It is magnetic after cold working and is used in railway vehicles.

    3, 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.

    4, 201 is high in manganese, the surface is very bright with dark bright, manganese is high and easy to rust. 304 contains more chromium, the surface is matte, no rust. The two are put together to compare. The most important thing is the corrosion resistance is different, the corrosion resistance of 201 is very poor, so the price is much cheaper. Because 201 contains low nickel, the price is lower than 304, so the corrosion resistance is not as good as 304.

    5, the difference between 201 and 304 is the problem of nickel. And the price of 304 is now more expensive, but at least 304 can guarantee that it will not rust during use. (Experiment with stainless steel potion)

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