Latest Patents
Arai's latest patents include innovations in steel sheets designed for easy-to-open cans. One of his inventions relates to a steel sheet that can be used in the manufacture of can ends, which traditionally relied on aluminum. This steel sheet consists of 0.06% to 0.25% carbon, with the remainder being primarily iron and unavoidable impurities. The fine cementite particles within the steel sheet, averaging between 0.05 µm and 0.5 µm in diameter, significantly reduce the can-opening force required and improve the formability of the can end, even at high strengths. Another patent focuses on a steel sheet for the production of DrD or DI cans, featuring a cold-rolled steel sheet coated with a solvent-type thermosetting paint that contains ethylene-vinyl acetate copolymer.
