EXHIBIT 99.1

Quanex Announces Definitive Agreement to Purchase Atmosphere Annealing, Inc.

HOUSTON, Dec. 13, 2006 (PRIME NEWSWIRE) -- Quanex Corporation (NYSE:NX), an industry-leading manufacturer of value-added engineered materials and components for the vehicular products and building products markets, announced today that it signed a definitive agreement with Maxco, Inc., to purchase the assets of Atmosphere Annealing, Inc. (AAI), a wholly owned subsidiary of Maxco, Inc. The acquisition is subject to governmental approval and the approval of Maxco, Inc. shareholders. The purchase is expected to close on or about February 1, 2007. Terms were not disclosed.

Atmosphere Annealing Inc. 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 primarily on automotive powertrain applications.

"AAI is an excellent example of the type of acquisition we seek to continue to grow MACSTEEL," said Raymond Jean, Quanex chairman and chief executive officer. "AAI will allow us to offer additional value-added services for our Tier 1 and Tier 2 automotive customers. Today, about 50% of AAI's new business is in the fast growing automotive transplant market, where MACSTEEL also continues to achieve market penetration. Like MACSTEEL, AAI's sales approach is differentiated through the application of metallurgical solutions."

Quanex is an industry-leading 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.
