Acerinox, a global leader in stainless steel and high-performance alloys, has officially acquired Haynes International through its U.S. subsidiary, North American Stainless (NAS). This strategic acquisition enhances Acerinox’s capabilities in high-performance alloys, particularly in the U.S. aerospace sector, while strengthening its market position globally.

“We are thrilled to welcome Haynes to the Acerinox family,” said Bernardo Velázquez Herreros, CEO of Acerinox. “This addition expands our product offerings and accelerates our growth in the high-performance alloys segment. With Haynes’s skilled team and rich legacy, we’re confident in achieving significant advancements together.”
