Waste Incinerators

After examining practical structural materials for use in the high-temperature environments of waste incinerators, it was found that a Ni-Cr-W casting alloy is promising. However, the corrosion reaches its peak in the vicinity of 900°C. This peak is related to the behavior of chlorides that form in the interior of the alloy. As the chlorides continuously generate and decompose, the Cl recycles, accelerating corrosion. It is thought that when the temperature rises, the chlorides vaporize outside the alloy, suppressing Cl recycling and thus reducing the amount of corrosion. Adding Al to the alloy generates highly volatile AlCl3, making it possible to prevent the accumulation of chlorides in the vicinity of 900°C and lower the corrosion peak. As a result of conducting exposure testing for a year at an actual incinerator, it was demonstrated that adding Al is an effective way to improve corrosion resistance.

Abstract The AL-6XN PLUS alloy is an enhanced version of the AL-6XN alloy (see Alloy Digest SS-494, May 1988). Both satisfy the composition requirements of UNS N08367, but AL-6XN PLUS contains a greater concentration of the alloying elements (Cr, Mo, and N) which promote corrosion resistance. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-923. Producer or source: Allegheny Ludlum Corporation. Originally published April 2005, revised June 2005.
