What is the difference between stainless steel 201, 304 and 316？

Stainless steel, as a common metal material, is everywhere in our lives. But do you really know about stainless steel? Do you know what the difference is between 201, 304 and 316 types of stainless steel? Don't worry, today we will find out!

First of all, let's understand the basic knowledge of stainless steel. Stainless steel is a kind of metal material that can resist corrosion and oxidation, and has excellent durability and aesthetics. Stainless steel models are mainly divided according to their chemical composition and properties.

Next, let's compare the three kinds of stainless steel 201, 304 and 316 in detail.

1. **201 stainless steel ** : 201 stainless steel is a stainless steel with low nickel content, and the price is relatively cheap. Its corrosion resistance is relatively weak and it is not suitable for use in humid environments. Due to its weak anti-rust ability, it needs to pay attention to maintenance when using.

2. **304 Stainless steel ** : 304 stainless steel is a widely used model, also known as food grade stainless steel. It contains enough nickel and has good corrosion resistance and processing properties. 304 stainless steel is widely used in the home, industry and medical fields, such as kitchenware, tableware and medical equipment.

3. **316 stainless steel ** : 316 stainless steel is a kind of stainless steel containing molybdenum element, with better corrosion resistance and high temperature performance. It is suitable for extreme environments such as Marine engineering, chemical industry and high temperature environments. Compared with 304 stainless steel, 316 stainless steel is more corrosion resistant and can resist the erosion of various acid and alkali substances.

By comparing the chemical composition and properties of these three stainless steels, we can draw the following conclusions:

* 201 stainless steel is suitable for occasions with low rust prevention requirements;

* 304 stainless steel is suitable for home and industrial fields;

* 316 stainless steel is suitable for Marine engineering, chemical industry and other extreme environments.

Now, you should have a deeper understanding of the difference between 201, 304 and 316 stainless steel.

When choosing stainless steel products, the appropriate stainless steel model can be selected according to the actual needs and the use environment.

Remember, the right choice of stainless steel can extend the service life and improve the safety performance!
