The Difference Between 201 And 304 Stainless Steel-Sushang Steel

There are many types of stainless steel, and each series has its own unique performance characteristics. Generally, stainless steel can be roughly divided into three categories: 200 series, 300 series, and 400 series. Among these three series, the 300 series is the most widely used. The 200 series and 400 series can be used as substitutes for the 300 series to a certain extent. However, strictly speaking, the 400 series does not belong to stainless steel, but is called "ferritic stainless steel" because it does not contain nickel, so it is magnetic and can be attracted by magnets. The 200 series and 300 series have nickel, so they are not magnetic and cannot attract iron. So today, I will introduce two types of stainless steel to you, which are representatives of the 200 series and the 300 series respectively. Next, we will explore the differences between these two types of stainless steel in depth.

Characteristics of 201 stainless steel

1. The corrosion resistance of 201 stainless steel is relatively weak, mainly because it contains less nickel, which reduces its corrosion resistance.

2. Generally speaking, nickel is a relatively precious metal. Since the nickel content in 201 stainless steel is low, the price of 201 stainless steel is relatively low.

3. 201 stainless steel has high strength and is suitable for manufacturing equipment or structures that need to withstand greater pressure.

4. 201 stainless steel is likely to rust in certain acidic environments, so when choosing stainless steel, you must make a certain assessment of the use environment.

Characteristics of 304 stainless steel

1. Since 304 stainless steel has rich chromium and nickel components, it has very good corrosion resistance. 304 stainless steel is often used in food processing equipment, medical equipment, chemical equipment and other fields with high hygiene requirements.

2. The surface of 304 stainless steel is smooth and easy to clean and maintain, so it is also widely used in kitchen utensils and tableware. 3. Although its thermal conductivity is weak, 304 stainless steel can still maintain good stability in high temperature environments and is suitable for applications in high temperature environments.

The difference between 201 stainless steel and 304 stainless steel

1. 201 stainless steel has a lower nickel content and is relatively cheap, while 304 stainless steel has a higher nickel content, better corrosion resistance, better quality, and a relatively higher price. Generally speaking, 304 stainless steel is about twice as expensive as 201 stainless steel.

2. 201 stainless steel has high strength and is suitable for high-pressure equipment. It is magnetic after cold processing and is used for railway vehicles. 304 is the most widely used stainless steel and heat-resistant steel. It is used for food production equipment, general chemical equipment, nuclear energy, etc.

3. 201 has a higher manganese content, and the surface is very bright with a dark luster. It is easy to rust with a high manganese content, so you need to carefully choose the use environment, while 304 stainless steel has better corrosion resistance.

4. Stainless steel is not easy to rust because chromium-rich oxides are formed on the surface of the steel body to protect the steel body. 201 material is a high-manganese stainless steel with greater hardness than 304, high carbon and low nickel.

5. The mechanical properties of 201 stainless steel and 304 stainless steel are different. The hot and cold processing performance and welding performance of 201 are not as good as 304. 201 stainless steel is more sensitive to hot cracks.
