304 VS 316 stainless steel - what's the difference?

The main difference between 304 and 316 stainless steel lies in their chemical composition and corrosion resistance. 304 stainless steel contains 18% chromium and 8% nickel, while 316 stainless steel also contains 2-3% molybdenum in addition to these elements.

316 stainless steel has stronger corrosion resistance and performs better in chloride environments and acidic conditions, making it suitable for harsh environments such as marine equipment and chemical fields. 304 stainless steel is commonly used in general applications such as interior decoration and food processing equipment, and is more cost-effective than 316 stainless steel. The choice between 304 or 316 depends on specific requirements, such as corrosion resistance requirements and budget considerations.
