1. Types and chemical components

2. Features/applications


We provide steels responding to various needs of high strength, carburizing time reduction and alloy-savings.
(1) Improved gear fatigue strength enables higher-capacity, reduction in size, weight and component count of units .
(2) Reducing carburizing time allows the reduction of takt time, cost and CO2 emissions.
(3) Alloy-savings reduce resource risks and cost.

Major applications

Automotive/Truck: Variable gears, counter gears, differential gears, input/output shafts, inner/outer races
Construction machineries: Gears, pinions, cylinder shafts
