Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying unaudited consolidated condensed financial statements include the accounts of SIFCO Industries, Inc. and its wholly-owned subsidiaries (the “Company”). All significant intercompany accounts and transactions have been eliminated. The U.S. dollar is the functional currency for all of the Company’s U.S. operations and its Irish subsidiary. For these operations, all gains and losses from completed currency transactions are included in income currently. Foreign currency translation adjustments are reported as a component of accumulated other comprehensive loss in the unaudited consolidated condensed financial statements. These unaudited consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s fiscal 2014 Annual Report on Form 10-K. The results of operations for any interim period are not necessarily indicative of the results to be expected for other interim periods or the full year.
Net Income per Share	Net Income (loss) per Share The Company’s net income (loss) per basic share has been computed based on the weighted-average number of common shares outstanding. Net income (loss) per diluted share reflects the effect of the Company’s outstanding stock options, restricted shares and performance shares under the treasury stock method.
Derivative Financial Instruments	Derivative Financial Instruments The Company uses an interest rate swap agreement to reduce risk related to variable-rate debt, which is subject to changes in market rates of interest. The interest rate swap is designated as a cash flow hedge. At September 30, 2014, the Company held one interest rate swap agreement with a notional amount of $4,000. The interest rate swap matured as of December 31, 2014. Cash flows related to the interest rate swap agreement are included in interest expense. The Company’s interest rate swap agreement and its variable-rate term debt are based upon LIBOR. During the first quarter of fiscal 2015, the Company’s interest rate swap agreement qualified as a fully effective cash flow hedge against the Company’s variable-rate term note interest risk.
Reclassifications	Reclassifications Certain prior period amounts were reclassified to conform to the current consolidated financial statement presentation.
