316 vs 2205 vs 201 Stainless Steel – What’s the Difference? 

316, 2205, and 201 stainless steels are all commonly seen types of stainless steel in daily life. But 316 vs 2205 vs 201 stainless steel – What’s the difference? In fact, their differences mainly focus on composition, performance, corrosion resistance, and use. In this article, we will explore the differences between 316 and 2205, 201 stainless steels in depth to help you better understand their differences so that you can make more informed choices in various application scenarios.

316 Vs 2205 Vs 201 Stainless Steel – What’s the Difference? 

316 Vs 2205 Vs 201 Stainless Steel – 1. Chemical composition:

316 stainless steel: 316 stainless steel is an austenitic stainless steel with a main composition of about 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. It also contains small amounts of titanium, niobium, and other elements.
2205 stainless steel: 2205 stainless steel is a duplex stainless steel consisting of approximately 22% chromium, 5-6% nickel, 3% molybdenum, and approximately 0.15-0.25% nitrogen.
201 stainless steel: 201 stainless steel is an austenitic stainless steel containing approximately 16-18% chromium, 3.5-5.5% nickel, and approximately 0.05-0.25% nitrogen.

316 Vs 2205 Vs 201 Stainless Steel – 2. Corrosion resistance:

316 stainless steel: 316 stainless steel has excellent corrosion resistance, especially for acid and chloride environments, and is suitable for applications with high corrosion resistance requirements such as marine environments and chemical processing equipment.
2205 stainless steel: 2205 stainless steel has high corrosion resistance, especially for stress corrosion cracking in chloride media. It is widely used in the chemical industry, marine engineering, petroleum, and other fields requiring high strength and corrosion resistance.
201 stainless steel: 201 stainless steel has weaker corrosion resistance compared to 316 and 2205, and therefore is usually used for general applications in low-corrosion environments such as decorative materials and kitchenware.

316 Vs 2205 Vs 201 Stainless Steel – 3. Application scope:

316 stainless steel: 316 stainless steel is widely used in chemical processing equipment, marine environments, pharmaceutical equipment, food processing equipment, medical devices, and other fields requiring excellent corrosion resistance.
2205 stainless steel: 2205 stainless steel is commonly used in marine engineering, chemical industry, oil and gas industry, paper industry, and other applications where high corrosion resistance and strength are required.
201 stainless steel: 201 stainless steel is mainly used for general applications such as architectural decoration, kitchenware, and furniture that do not require high strength and corrosion resistance.
