In Japan's industrial sector, the steel and chemical industries, which are fundamental to the economy, use large quantities of oxygen and nitrogen as oxidizing agents and atmospheric gases. In the metal processing fields such as automotive, machinery, and construction, oxygen, nitrogen, argon, and acetylene are used for cutting, welding, and heat treatment, contributing to improvements in quality and productivity. In the rapidly growing electronics industry, nitrogen, argon, and electronic material gases are used in large amounts. We provide the necessary gases to all industrial sectors at the right time and in the optimal supply method, both in Japan and overseas.
