Frequently Asked Questions
304 stainless steel is a general-purpose grade with good corrosion resistance and is suitable for most applications. 316 stainless steel contains molybdenum, which provides superior corrosion resistance, especially in marine and chemical environments. 316 is often preferred for applications where exposure to chlorides or harsh chemicals is expected.
