         The Duriron Company, Inc. ("Duriron") filed the Registration Statement
on Form S-4 (the "Registration Statement") with respect to which this
Post-Effective Amendment No. 1 is being filed for the purpose of registering
shares of Duriron's Common Stock, par value $1.25 per share ("Duriron Common
Stock"), being issued by Duriron in connection with the merger of a
wholly-owned subsidiary of Duriron into Durametallic Corporation
("Durametallic").  Under the terms of the Agreement and Plan of Merger (the
"Merger Agreement") dated as of September 11, 1995 among Duriron, Wolverine
Acquisition Corp. and Durametallic, at the effective time of the merger on
November 30, 1995, each option outstanding under the Durametallic Corporation
1991 Stock Option Plan (the "Durametallic Option Plan") became exercisable for
Duriron Common Stock, on the basis of 3.1132 shares of Duriron Common Stock for
each share of Durametallic's Common Stock, $5.00 par value per share
("Durametallic Shares"), for which the option was exercisable prior to the
effective time of the merger, at an exercise price per share equal to the
exercise price per share in effect prior to the effective time of the merger
divided by 3.1132.  In addition, as required by the Merger Agreement, the
Durametallic Corporation Executive Incentive Bonus Plan (the "Durametallic
Bonus Plan") was amended to provide that, after the effective time of the
merger, persons entitled to receive Durametallic Shares under the Durametallic
Bonus Plan will receive, instead, on the same terms and conditions, Duriron
Common Stock, on the basis of 3.1132 shares of Duriron Common Stock for each
Durametallic Share otherwise issuable under the Durametallic Bonus Plan.

         This Post-Effective Amendment No. 1 on Form S-8 is being filed for the
purpose of registering the offer and sale of the Duriron Common Stock (the
"Plan Shares") that may be issued in lieu of Durametallic Shares upon the
exercise of options granted under the Durametallic Option Plan and under the
Durametallic Bonus Plan in accordance with the Merger Agreement.  The 6,458,558
shares of Duriron Common Stock registered pursuant to the Registration
Statement were sufficient to include the Plan Shares.
