Stainless Steel 40508518 4mm PCB Drilling Machine Collet

Stainless steel refers to steel that is resistant to corrosion by weakly corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practical applications, steel that is resistant to corrosion by weakly corrosive media is often referred to as stainless steel. Stainless steel is an extremely thin, strong and stable chromium-rich oxide film (protective film) formed on its surface. Prevent oxygen atoms from infiltrating and continuing to oxidize, and obtain rust resistance.
