Surface modification technology that enhances the wear resistance of stainless steel, making it as durable as coding!
At Air Brown, we offer new technologies and services to enhance the strength, wear resistance, and corrosion resistance of various types of stainless steel (Austenitic, Duplex, Martensitic, Ferritic, etc.). "EXPANITE" is not just a coating; it is a high-quality, high-performance technology that directly modifies the surface of stainless steel (with thickness depending on the process, etc.). We provide three processes tailored to specific applications and purposes. The surfaces of the processes are also very clean, eliminating the need for cleaning (depending on the application and purpose). ■ Benefits of Expanite Treatment - Hardness increase reaching surface hardness of 1,000-1,500 HV - Improved galling resistance and metal fatigue resistance - Enhanced corrosion resistance - No risk of peeling or flaking For more details, please contact us or download the catalog.

Company information
The company founded by British trader Albert Richard Brown (A.R. Brown) in Yokohama is its origin. A.R. Brown brought the training ship "Meiji Maru," which is currently displayed at Tokyo University of Marine Science and Technology, from Britain during the Meiji era and participated in the establishment of the university's predecessor, the College of Shipping, contributing to the foundation of the Imperial Japanese Navy. He also worked hard to promote lighthouses in Japan and served as the first manager of Nippon Yusen. It was A.R. Brown who first sold a television to the Emperor. After going through history, it has now become a purely domestic company, but it has inherited A.R. Brown's spirit and has developed into a scientific and technological trading company where specialized salespeople sell new and unique quality products. With the management philosophy of "introducing cutting-edge technology products with an adventurous spirit and creating value," the company not only sells but also listens to customer needs, striving to provide products that are truly helpful to customers. The sales bases are located in Tokyo (headquarters in Ginza), Osaka, and Nagoya. Domestic affiliated company: Brown Technologies Co., Ltd.
