Performance comparison of 201 stainless steel strip and 304 stainless steel strip

2022-11-14
1. Mechanical properties: In terms of fatigue strength, the hardness of 201 stainless steel strip is higher, but the toughness is not as good as that of 304 stainless steel strip, and the fatigue resistance of 04 stainless steel strip is more durable.

2. Color: 201 stainless steel strip has high manganese content, bright surface and dark brightness. High manganese content is easy to rust. 304 stainless steel strip contains more chromium, the surface is dull and does not rust.

3. Anti-rust: stainless steel is not easy to rust because the chromium-rich oxide formed on the surface of the steel can protect the steel. 201 stainless steel strip belongs to high manganese stainless steel, which has higher hardness, high carbon content and low nickel content than 304 stainless steel. In the same outdoor environment, 304 stainless steel strip will not rust for 3-4 years, and 201 stainless steel strip will rust after 6 months;

4. Composition: The difference between 201 stainless steel strip and 304 stainless steel strip is that it contains nickel: 201 is composed of 17Cr-4.5Ni-6Mn-N, which is a substitute for 301 stainless steel strip. It is magnetic after cold working and is used in railway vehicles. 304 is composed of 18Cr-9Ni, which is a widely used stainless steel and heat-resistant steel. Used in food production facilities and equipment, common chemical equipment, nuclear energy, etc.
