Item 8.01. Other Events

          On January 25, 2005, Quanex Corporation (the "Company") and the trustee for the Company's 2.50% Convertible Senior Debentures due May 15, 2034 (the "Debentures") executed a supplemental indenture to the indenture governing the Debentures. The indenture previously allowed the Company, on the date the Debentures first become convertible, to make an election to settle the principal amount of its obligation with either common stock, cash or a combination of the two. The amendment effectuated by the supplemental indenture permits the Company to elect the method by which the principal amount of the obligation will be settled in advance of when the Debentures become convertible. The supplemental indenture is attached to this Form 8-K as Exhibit 99.1 and incorporated herein by reference.

          On January 26, 2005, the Company issued a press release announcing that it has irrevocably elected to settle the principal amount of its Debentures in cash when they become convertible and are surrendered by the holders thereof. The press release dated January 26, 2005 is attached as Exhibit 99.2 and incorporated herein by reference.
