Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 22. SUBSEQUENT EVENTS On October 7, 2011, The Company announced its decision to exit the business in CMCS by way of sale and/or closure. During 2011, the Company made operational improvements in the business but not to a level which would restore profitability for the long run. Additionally, delayed entry in the European Union, cyclical demand for tubular products, unsustainable losses and increased demand for capital resources resulted in the decision to exit the business. The operation will service any existing customer commitments and the Company expects to wind down operations and liquidate inventory over the next several months. In connection with this decision, the Company expects to incur severance and other closure costs between $25 million and $40 million in fiscal 2012.
