There are several common types of stainless steel materials on the market today: 2 series stainless steel, 3 series stainless steel, and 4 series stainless steel.
The carbon content of the 2 series stainless steel is relatively high, resulting in low comprehensive performance, poor strength and corrosion resistance, and is generally used for low-end products.
3 series stainless steel is the best choice, of which the 304 and 316 series are the most commonly used. Compared with 2 series stainless steel, 304 has higher alloying element content and lower carbon element content, resulting in higher strength, higher corrosion resistance and better overall performance. 316 stainless steel is a performance-optimized version of 304 stainless steel, which is used in high-end products and is a material with the best physical and chemical properties.
For material selection, low-end products do not have any rigid requirements for the material itself, and you can choose 2 series stainless steel; for the comprehensive performance of steel, it is recommended to choose 304 series materials; for high-end electronic components, import and export products, it is recommended to use 316 Series stainless steel.
