Latest Patents

Atsumi Hatano holds a patent for a unique steel composition designed for gears. This steel consists essentially of 0.10-0.30 wt % of carbon, not more than 1.0 wt % of silicon, not more than 1.0 wt % of manganese, 1.50-5.0 wt % of chromium, with the balance being iron and impurities. The gear produced from this steel undergoes a process of carbonizing-hardening-tempering or carbonitriding-hardening-tempering, resulting in a hardened surface layer. The carbon content in this hardened layer ranges from 0.7 to 1.3 wt %. The specific relationship between carbon, silicon, and chromium ensures that the gear exhibits superior pitting-resistance and wear-resistance.
