Applications/Examples of results
Steel is widely used as a steel material for screws due to its availability, strength, and toughness. Based on carbon steel, which primarily consists of iron (Fe) and carbon (C), alloy steels that have been heat-treated or contain additions such as chromium and molybdenum are used according to their shape, strength, and corrosion resistance for various applications. Nickel plating is a widely used decorative plating that has a mirror-like luster. Its rust resistance is superior to that of chromate treatment or trivalent chromate treatment. To enhance adhesion to screws and improve rust resistance, a copper plating is applied as a base layer under the nickel plating.
