Stainless steel and 304 stainless steel differ significantly in a number of ways. First of all, the materials of the two are different, stainless steel is a general term, covering many metal materials with anti-rust ability, and 304 stainless steel is one of the specific types, belonging to austenitic stainless steel. Secondly, the uses of the two are different, stainless steel is widely used in construction, home, chemical and other fields, while 304 stainless steel is widely used in food, medical, environmental protection and other fields because of its excellent corrosion resistance and processing performance. In addition, the characteristics of the two are also different, stainless steel has the characteristics of rust resistance, corrosion resistance, good processing performance, etc., while 304 stainless steel is more wear-resistant, high-temperature resistant, and has better comprehensive performance on this basis.
In terms of composition, 304 stainless steel is purer than ordinary stainless steel and contains fewer impurity elements. Specifically, 304 stainless steel has a carbon content of less than 008%, chromium content higher than 18%, nickel content higher than 8%, these chemical components determine its excellent performance. At the same time, 304 stainless steel also has good welding and ductility, which can meet various processing needs.
In general, stainless steel and 304 stainless steel, although both fall into the category of stainless steel, have significant differences in material, use, properties, and composition. When choosing a material, it needs to be considered according to the actual needs and use.
