Winsco Metal's 201 and 304 stainless steel sheets are two kinds of stainless steel sheet products made of different materials, and they have certain differences in chemical composition, mechanical properties and application fields.
1. The difference in chemical composition: The main chemical composition of Winsco Metal 201 stainless steel sheet is 17% to 19% chromium, 4% to 6% nickel and 0.15% to 0.25% nitrogen, a small amount of manganese, silicon and phosphorus, etc. The main chemical composition of Winsco Metal 304 stainless steel sheet is 18% to 20% chromium, 8% to 10.5% nickel and a small amount of carbon, manganese, silicon, phosphorus and sulfur.
2. The difference in mechanical properties: Winsco Metal 201 stainless steel sheet is weaker than Winsco Metal 304 stainless steel sheet in terms of mechanical properties, its strength and hardness are relatively low, but it has good plasticity and machinability.
3. Corrosion resistance: Winsco Metal 304 stainless steel sheet is better than Winsco Metal 201 stainless steel sheet in terms of corrosion resistance. Due to the higher content of nickel and chromium, Winsco Metal 304 stainless steel sheet can resist more corrosive media, such as acid, alkali, etc., and has a longer service life.
4. Magnetism: Winsco Metal 201 stainless steel sheet is an iron-based alloy with certain magnetic properties; while Winsco Metal 304 stainless steel sheet is a non-ferrous alloy with no magnetic properties. This is also an important feature to distinguish two kinds of stainless steel sheets. In some applications, it is necessary to consider whether the material is magnetic.
5. Price: Winsco Metal 201 stainless steel sheet is cheaper than Winsco Metal 304 stainless steel sheet due to the difference in its chemical composition and mechanical properties. Therefore, in some low-end applications, the market share of Winsco Metal 201 stainless steel sheet is higher.
6. Processing performance: Winsco Metal 201 stainless steel sheet has good machinability, and can be formed and processed in a variety of ways, such as bending, punching, cutting, welding, etc.; while Winsco Metal 304 stainless steel sheet is more difficult to process and requires professional processing technology.
7. Differences in application fields: Due to the difference in chemical composition and mechanical properties, Winsco Metal 201 stainless steel sheets have certain market demands in some low-end and mid-end application fields, such as kitchen utensils, home decoration, architectural decoration, etc. The Winsco Metal 304 stainless steel sheet is widely used in high-end fields, such as food processing, medical treatment, chemical industry, marine engineering, etc.
