The difference between stainless steel SUS304 and SUS316

SUS304 and SUS316 are two common stainless steel materials. Stainless steel SUS304 contains 18% chromium and 8% nickel, suitable for general environments, and has a relatively low price. Stainless steel SUS316 has added 2% molybdenum on this basis, improving its corrosion resistance, especially in chloride environments.

Stainless steel SUS316 is suitable for applications such as marine and chemical industries that require stronger corrosion resistance, and has superior corrosion resistance performance. In contrast, stainless steel SUS304 is commonly used in general application fields such as construction and kitchen equipment.

SUS316 stainless steel has better tensile strength and wear resistance, making it suitable for applications that require higher strength, such as the aerospace industry. However, the cost is also high and needs to be selected based on demand.

In fields such as food processing and medical device manufacturing, stainless steel SUS316 is more preferred due to its stronger hygiene and corrosion resistance. Taking into account the usage environment, performance requirements, and budget, it is crucial to choose the appropriate type of stainless steel.
