Refractory anchors of 309 stainless steel lasted only two months at 1600°F (871°C) in a manure incinerator. After six months' service HAYNES® HR-160® alloy exhibited only slight signs of attack. | ||||||||

 |
HAYNES® 556TM alloy was chosen for components of waste ash handling system operating at 1650°F (899°C). It has more than doubled the life of previously used stainless steel. | ||||||||
| This retort of HAYNES® HR-160® alloy is used in the incineration of furnace dust. |  |

Critical parts of this deep-well hazardous waste disposal system are made of HASTELLOY® C-22® alloy. It is designed to handle sulfuric, nitric, hydrochloric, hydrofluoric and chromic acids as well as leachates and alkalis contaminated with iron, copper or nickel ions. | ||||||||
| HASTELLOY® C-22® alloy was selected to replace FRP because of its durability and corrosion resistance. The fan is handling off gases from the incineration of radioactive and hazardous wastes. |  |

HASTELLOY® C-22® alloy plays a key role in the safe treatment of nuclear waste. Alloy vessels are used to concentrate radioactive wastes which are then sealed in glass for safe disposal. | ||||||||
HASTELLOY® C-22® alloy was specified as the prototype venture scrubber for a nuclear waste incinerator at Los Alamos National Laboratory. Corrosion tests wre made in a "worst case" situation involving NaCl, FeCl3, NaF, HCl and H2SO4 environment at 167°F (75°C). The C-22 alloy outperformed alloys C-276, 625 and AL-6XN®. In fact, even the cast weld structure of C-22® alloy exhibited better resistance to corrosion than wrought 625 alloy. AL-6XN is a registered trademark of Allegheny Ludlum Steel Corp. |
