What kind of Steel Does Stainless Steel Refer to?

  • Stainless steel is the abbreviation of stainless and acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have rust resistance are called stainless steels; and steels that are resistant to chemical corrosion media are called acid-resistant steels.

    It is generally believed that Sheffield metallurgist Harry Brearley discovered stainless steel in 1913. He is experimenting with different types of weapons for use in weapons and noticed that 13% of chrome steel did not corrode after several months.

    Due to the difference in the chemical composition of the two, their solid resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally non-corrosive. The term "stainless steel" not only refers to a single type of stainless steel but also refers to more than one hundred industrial stainless steel. Each stainless steel developed has good performance in its specific application field. The key to success is to understand the purpose first, and then determine the correct steel grade. There are usually only six steel grades related to the application of building construction. They all contain 17-22% chromium, and better steel grades also contain nickel. The addition of molybdenum can further improve atmospheric corrosion, especially the corrosion resistance of the chloride-containing atmosphere.
