Supporting the progress of home appliances and office automation equipment that make our lives comfortable.
Pre-coated steel sheet "VIEWKOTE™" of Nippon Steel & Sumitomo Metal provides products meeting your needs with a combination of various paints or base steel sheets uniquely developed by NSSMC through the epoch-making coating system.
To prevent increase in temperature due to heat from inside the product, we have developed a high-heat-absorption-type steel, VIEWKOTE, which can release heat outside by applying a heat absorption film to the steel sheet used for the inner casing. It has been used for audio products, flat-panel TVs, TV tuners, etc.
Scratches on the home appliance surface can be made almost inconspicuous by developing an orange peel pattern. Non-random irregularities are accurately controlled. Development of beautiful, fine, and uniform irregularities will meet advanced appearance requirements of home appliances. It is used for the side panels of outdoor air conditioner units or refrigerators.
Easy discharge of charged static electricity results in non-attraction of dust. In addition, antistatic type VIEWKOTE™, which is effective in prevention of charge due to friction, has been developed. In comparison with conventional coated steel sheet, it is successful in reducing charge voltage to 1/4. It has been used for the side panels of refrigerators.
We have developed an inclined-type coat in which only the coat surface is hardened and the inside is kept soft. In addition, self-cleaning, in which stains are washed off with rainwater, is achieved by designing a coat surface easily adapted to water and allowing entry of water between pollutants and the coat film. It is used for outdoor air conditioner units and heat pump boilers installed outdoors.
Further improvement of corrosion resistance
Since a dense protection film is formed on the surface, corrosion reaction can be controlled. Corrosion resistance is better than conventional hot-dip galvanized steel. It contributes to long life or life cycle cost of home appliance products.More Information
The shielding function, by which oxygen or water being the cause of corrosion does not penetrate, the self-repair function, which recovers the coat film if the surface is damaged, and the coat adhesion function share the substance non-hexavalent chromium, not a single substance. The same characteristics as chromate film that contains hexavalent chromium are achieved.Contact us
After placing three layers of nickel, tin, and zinc respectively in electroplating, the plating is turned into alloy by heating and melting. Nippon Steel & Sumitomo Metal has been successful in controlling the growth of whiskers. Lead-free products not containing lead, which is an environmentally hazardous substance, have been achieved.Contact us
High function material using magnetic characteristics of iron
The world's highest-level high-performance non-oriented electrical steel sheet with high magnetic flux density and low iron loss has been developed to contribute to improvement of the energy-saving performance of home appliances.Contact us
Key technology of induction heating
Nippon Steel & Sumitomo Metal produced a two-layer clad steel sheet joining aluminum to the uniquely developed high-function stainless steel from 1988. Outside stainless steel excellent in heating is efficiently heated by an IH magnetic field line, and the aluminum with high heat conductivity inside quickly distributes the heat over the entire furnace.More Information
Easily removable fingerprints
While using stainless steel characteristics with a beautiful metal gloss and excellent corrosion resistance, clear coating is provided on the surface. Fingerprints on the surface are not conspicuous and function improvement for easy removal (fingerprint resistance) is achieved.
Achievement of resource saving by world-first addition of tin
In the NSSC FW™ series, corrosion resistance is improved while reducing addition of chromium (Cr) based on the epoch-making new technology that greatly improves the corrosion resistance of the ferrite (chromium based) stainless steel by adding a trace of tin (Sn), and workability is also achieved.
