The difference between 201 stainless steel rod and 304 stainless steel rod

In this article, I will give you a detailed introduction to the maintenance skills of stainless steel rods and the difference between 201 and 304 of different materials. Let's take a look in the article!

1. Price

201 stainless steel rod and 304 stainless steel rod are two products that we can often see and commonly use in the market. The ingredients of these two products are different, and their prices are also different. The quality and performance of 304 stainless steel rods are better, so the price will be more expensive, while 201 stainless steel rods are slightly worse.

2. Ingredients

The composition of 201 stainless steel rod is 17Cr-4.5Ni-6Mn-Ni, and the composition of 304 stainless steel rod is 18Cr-9Ni. The difference between 201 and 304 is the problem of nickel content. And the price of nickel is now more expensive, but 304 can at least guarantee that it will not rust during use.

3. Purpose

201 stainless steel rods are all used in railways and vehicles, and 304 stainless steel rods are currently widely used products, which are used in food production equipment, general chemical equipment, nuclear energy, etc.

4. Performance

The corrosion resistance between the two is different. The content of manganese contained in the 201 stainless steel bar is relatively high, and it is relatively easy to rust. 304 stainless steel contains more chromium, so it is not easy to rust and is more corrosion-resistant.

5. Appearance

The surface of the 201 stainless steel rod is very bright and dark, and the surface of the 304 stainless steel rod is matte.
