Latest Patents

Masahiko Sato holds a patent for a method for heat treatment of steel. This method involves carburization hardening of steel to form carburized steel, followed by a second hardening process. The technique effectively reduces the grain size of steel while precipitating carbonitrides within the grains, thereby increasing the strength of the heat-treated steel. The process includes heating the steel to a first austenitic temperature range in a carburizing gas atmosphere, cooling it to a martensitic temperature range, and quenching the steel. The second hardening involves heating the carburized steel to a second austenitic temperature range in a similar atmosphere and quenching it again.
