405 stainless steel is a high-alloy stainless steel material whose main components include chromium, nickel and copper.  It has good corrosion resistance and performs well in strong acid environments such as oxidizing acid, nitric acid, and sulfuric acid.  Therefore, it can be used in various corrosive environments, such as marine environment, chemical media, etc.  Besides, 405 stainless steel has good strength and toughness and can withstand greater pressure and impact.  At the same time, its processing performance is also good, and it can be used for cutting, bending, welding and other operations.  405 stainless steel has good heat resistance and can be used in high temperature environments.  This makes it advantageous in some applications requiring high temperature processing.
