Allegheny Technologies Inc. has announced that two of its operating units, Allegheny Ludlum and Allvac, are increasing prices for certain high-value products. Allegheny Ludlum is increasing prices by approximately 3% to 6% on its High Technology Alloys. These include all nickel-based superalloys, nickel-based alloys, high-strength alloys and super austenitic stainless alloys. Allegheny Ludlum will continue its use of the raw material surcharge mechanism already in effect for pricing these products. Allvac is increasing prices by approximately 3% to 6% on its nickel, titanium and specialty steel products. Allvac will continue its use of raw material indices to reflect changes in the market for raw materials for pricing these products. Raw material costs are major factors that affect pricing for these products. Prime and revert materials used in the manufacture of these products remain particularly volatile.
