The goal of this project was to accelerate the deployment of a new cast austenitic stainless steel, CF8C Plus, for new energy-relevant applications. The alloy was jointly developed by Oak Ridge National Laboratory (ORNL) and Caterpillar and is a low-cost, high-performance alternative to conventional cast steels and, in some cases, a cost-effective substitute for Ni-base alloys. CF8C-Plus steel won a 2003 R&D 100 Award, was patented in 2006 and was recognized as a new heat-resistant cast alloy grade by ASTM (HG10MNN). In 2006, CF8C-Plus was successfully commercialized for the Caterpillar Regeneration System (CRS) burner housing, which is needed for the operation of the ceramic diesel particular filter required in all on-highway diesel engines. To date, over 500 tons of CF8C-Plus have been cast for this single application. It was anticipated that the demonstrated commercial success in the CRS application could be translated to an expanded range of other transportation and power generation applications. Increased deployment of CF8C-Plus and Cu/W modified CF8C-Plus castings can lead to engines with increased efficiency and durability while lowering cost. Potential industrial partners that were targeted included automotive and diesel engine and part manufacturers as well as turbine, reciprocating engine and boiler manufacturers.
