Applications
Type 304/ 304L stainless steel is very common throughout the industry, especially in food processing, because it is not susceptible to acid corrosion in common foods. Therefore, this steel is very suitable for use in sinks, work surface, preparation areas and refrigerators. It is also an ideal material for pharmaceutical industry, such as clean room.
