304 stainless steel welded pipe/tube is a general-purpose austenitic stainless steel pipe composed of chromium (about 18%) and nickel (about 8%), with good corrosion resistance, heat resistance, formability and welding performance. Its surface is smooth and easy to clean, suitable for food processing, pharmaceuticals, chemicals, architectural decoration and household appliances.
304 stainless steel welded pipe/tube is made by welding process, with low cost and high production efficiency, which can meet the use requirements in moderately corrosive environment. In addition, it has excellent mechanical properties at room temperature and can withstand certain pressure and load. It is an economical, practical and widely used stainless steel pipe.
