Compared with 304 steel, 304N1 stainless steel has lower sulfur and manganese content, thus avoiding poor plasticity, increasing strength, and reducing the thickness of the material. This stainless steel has very good corrosion resistance, especially under acidic conditions. At the same time, its processing performance and welding performance are also very good. In the name of stainless steel, the word "N1" generally refers to a nitrogen-containing element. Adding N element to stainless steel gives it better corrosion resistance and higher strength.
