Daido Steel Co. Ltd., Nagoya, Japan, announced the successful start of operations at its new vacuum arc remelting (VAR) plant at the company’s Chita site. Developed in collaboration with ALD Vacuum Technologies, the plant is designed to increase production capacity for high-purity stainless steels and nickel alloys used in high-performance applications, particularly within the semiconductor industry.
The first VAR plant became operational in December 2024, with finished ingots now undergoing downstream processing. A second remelting unit is scheduled to begin operation in March 2025, with additional capacity expansions planned over the coming years.
The custom-designed VAR plant, supplied by ALD, enables the production of ultra-clean steel with a homogeneous microstructure, meeting the stringent quality standards required for semiconductor components. VAR-processed materials are known for their durability, purity, and consistency, making them ideal for critical industries.
Daido Steel’s investment reflects a strategic move to support the growing global demand for advanced materials in next-generation technologies. The company continues to position itself as a key supplier in the global supply chain for high-performance alloys.
