Stainless steel, as a widely used metal material, is favored by people because of its corrosion resistance, aesthetic and durable properties. Among the many types of stainless steel, 201 and 304 are two common types. So, when faced with the choice, we can not help but ask: 201 and 304 stainless steel, which is better?

First of all, we need to understand the basic characteristics of these two kinds of stainless steel. 201 stainless steel is an economical stainless steel material that contains less nickel and chromium elements. 304 stainless steel, also known as 18-8 stainless steel, has good corrosion resistance because it contains 18% chromium and 8% nickel.

Corrosion resistance

In terms of corrosion resistance, 304 stainless steel is significantly better than 201 stainless steel. The nickel and chromium content of 304 stainless steel gives it excellent corrosion resistance and can resist the erosion of most acid, alkali and salt solutions. 201 stainless steel, due to its low nickel and chromium content, has relatively poor corrosion resistance.

Aesthetics

In terms of appearance, the surface of 304 stainless steel is smoother and brighter, and has better aesthetics. The surface of 201 stainless steel may be rough and low gloss.

Application

Because 304 stainless steel has better corrosion resistance, it is usually used in occasions that require higher corrosion resistance, such as kitchen utensils, medical equipment, chemical equipment and so on. 201 stainless steel is more used in some occasions with low corrosion resistance requirements, such as architectural decoration, railings and so on.

Cost

From a cost perspective, the price of 201 stainless steel is usually lower than that of 304 stainless steel. This is because the nickel and chromium content of 201 stainless steel is low, and the production cost is relatively low.

In summary, 201 and 304 stainless steel have their own advantages and disadvantages. In the choice, we need to weigh according to the specific use environment and requirements. If higher corrosion resistance and aesthetics are needed, 304 stainless steel is undoubtedly a better choice. If the corrosion resistance requirements are not high, and you want to save on cost, then 201 stainless steel is also a good choice.
