6, With the steel number comparison table
The names of stainless steel vary from country to country. The market is often contacted by China and the United States. It is called the national standard and the American standard. The 200 series 300 series 400 series mentioned above is the American standard. The American standard is usually called because it is easy to understand. They are all American standards.
National standard ============ American standard
