EXHIBIT 99.1

Quanex Corporation Purchases Atmosphere Annealing, Inc.

HOUSTON, Feb. 2, 2007 (PRIME NEWSWIRE) -- Quanex Corporation (NYSE:NX) today announced that on February 1, 2007 MACSTEEL Atmosphere Annealing, Inc., a wholly owned subsidiary of Quanex, purchased substantially all the assets of Atmosphere Annealing, Inc. (AAI), a wholly owned subsidiary of Maxco, Inc.

AAI is a metal heat treating company with four plants located in the Midwest and fiscal 2006 sales of $46.6 million. Considered one of North America's leading heat-treating companies, AAI specializes in high volume, ferrous heat treating services for customers focused on automotive applications.

"The purchase of AAI builds upon MACSTEEL's ability to provide its Tier 1 and Tier 2 automotive customers with additional value added services and one-stop shopping. AAI, which focuses primarily on vehicular powertrain, steering and brake system components, serves many of the same customers as MACSTEEL," said Raymond Jean, Quanex chairman and chief executive officer. "In addition, half of AAI's new business is with the automotive transplant manufacturers, which should boost MACSTEEL's penetration of this growing market."

Quanex is a manufacturer of engineered materials and components for the vehicular products and building products markets. For further information, visit the Company's website at www.quanex.com.
