304, 316, and 316L are all grades of Stainless Steel that can be used to manufacture square tubes. Stainless steel square tubes are used in a variety of applications, including construction, automotive, and industrial.
304 stainless steel square tubes are made from an austenitic stainless steel that is non-magnetic and has excellent corrosion resistance. It is commonly used in food processing, chemical processing, and pharmaceutical industries.
316 stainless steel square tubes are made from a molybdenum-bearing austenitic stainless steel that has improved corrosion resistance compared to 304 stainless steel. It is commonly used in marine environments, chemical processing, and medical equipment.
316L stainless steel square tubes are a low carbon version of 316 stainless steel that has even better corrosion resistance and is easier to weld. It is commonly used in the same applications as 316 stainless steel.
All three grades of stainless steel square tubes can be polished for a mirror-like finish and are available in a variety of sizes and wall thicknesses. They can also be customized to meet specific requirements.
