Question:

What is the difference between 304 and 316 stainless steel?

Answer:

The main difference between 304 and 316 stainless steel is the presence of molybdenum in 316 stainless steel. This element enhances its corrosion resistance, making it more suitable for use in harsh environments such as marine applications or areas with high chloride exposure. Additionally, 316 stainless steel exhibits better resistance to pitting and crevice corrosion compared to 304 stainless steel.
The main difference between 304 and 316 stainless steel lies in their chemical composition. While both are highly corrosion-resistant, 316 stainless steel contains molybdenum, which enhances its resistance to certain chemicals and environments, making it more suitable for applications involving exposure to saltwater or harsh chemicals. Additionally, 316 stainless steel has a higher nickel content, providing better resistance to corrosion and staining. On the other hand, 304 stainless steel is more cost-effective and widely used in various industries for its good general corrosion resistance and versatility.
The main difference between 304 and 316 stainless steel lies in their composition and properties. While both are austenitic stainless steels, 304 contains 18% chromium and 8% nickel, whereas 316 has 16% chromium, 10% nickel, and 2% molybdenum. This addition of molybdenum provides 316 with enhanced corrosion resistance, especially against chlorides and other corrosive agents. As a result, 316 stainless steel is commonly used in marine environments and applications where exposure to chemicals or saltwater is expected. Conversely, 304 stainless steel is more affordable and suitable for general-purpose applications where corrosion resistance is not a primary concern.
