400 series stainless steel is an iron and carbon alloy alloy. This kind of stainless steel has the structure and iron element, so it has normal magnet properties. The 400 series of stainless steel has a strong high temperature resistance ability. Compared with the carbon steel, its physical and mechanical characteristics have further improved. Most 400 series stainless steel can be treated.

300 series stainless steel is a alloy material containing iron, carbon, nickel and chromium, a magnetic non -magnetic stainless steel material, which has better forgiveness characteristics than 400 series stainless steel. Because the austenitic structure of the 300 series of stainless steel, it has a strong corrosion resistance in many environments, and has a breakdown of corrosion caused by good anti -metal hyperbench, and its material characteristics are not treated with heat treatment Influence.

SUS304: It has good corrosion resistance, heat resistance, low temperature intensity and mechanical properties, good thermal processing such as stamping and bending, no heat treatment, and no magnetic. It is widely used in home supplies (type 1, 2 categories), cabinets, indoor pipelines, water heaters, boilers, bathtubs, car accessories, medical appliances, building materials, chemistry, food industry, agriculture, ship components, etc.
