Improving the economics of heat treatment facilities is often a question of raising the service temperature, which itself rests on the temperature capability of the alloys used. With the newly-developed alloy 602CA introduced to the market in 1992, there is now a nickel-base alloy available which provides sufficient high temperature strength and corrosion resistance up to 1,200 C, without any, special requirements on manufacturing and processing. Because of the excellent mechanical properties and corrosion resistance of this alloy it was possible to substitute uncooled all-metal furnace rolls for water-cooled asbestos rolls, in a continuous annealing furnace operating at up to 1,200 C. These rolls have now been in service for up to two years without any technical problems, and have proved themselves as a more economic and less environmentally dangerous, solution, This paper describes the mechanical properties and corrosion behavior of the new alloy, and gives some calculations on economic efficiency.
