  • Applied to high temperature materials. Because high temperature applications require relatively strong resistance to the material to prevent intergranular corrosion at low temperatures.
  • Because the surface can be a variety of surface processing, also widely used in the decoration industry filed.

The Different Standards

More about for 201/202 material

200 series stainless steel is in the period of World War II, as the 300 series stainless steel substitutes in the United States first developed successfully. At that time, as a result of the war, as a strategic material nickel is strictly controlled by the relevant countries, the United States nickel supply is seriously insufficient. In order to solve the serious shortage in the supply of nickel under the production and supply of stainless steel, the United States has developed a generation of nickel with manganese austenitic stainless steel of the new steel series.
