Custom Stainless Steel Retractable Spring Large Coil

       Stainless steel is the abbreviation of stainless acid-resistant steel. It is resistant to air, steam, water and other weakly corrosive media or stainless steel types called stainless steel. The steel grade is called acid-resistant steel.

       Due to "the difference in chemical composition, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless." Stainless steel is equivalent to more than one hundred industrial stainless steels. Many stainless steels developed have good performance in their specific application fields. The key to success is to first clarify the purpose, and then determine the correct steel grade. And construction, these contain 17 ~ 22% chromium, better steel also contains nickel. Adding molybdenum can increase the atmospheric corrosion, especially the corrosion resistance of chloride-containing atmosphere.
