Latest Patents

One of his latest patents is a heat treatment oil composition. This invention is characterized by a mixed base oil that includes a low-boiling base oil with a 5% distillation temperature ranging from 300 to 400°C, comprising not less than 5% by mass but less than 50% by mass. Additionally, it contains a high-boiling base oil with a 5% distillation temperature of 500°C or higher, making up more than 50% by mass but not more than 95% by mass. This quenching oil composition is designed to minimize fluctuations in hardness or quenching distortion of metal materials, even when multiple items are treated simultaneously. Another significant patent involves a quenching oil for reduced pressure quenching, which includes a base oil with a kinematic viscosity at 40°C of 40 mm/s or more, along with a vapor blanket breaking agent. This method allows for a wide range of cooling characteristics, effectively bridging the gap between cold and hot oil quenching.
