| Incineration of municipal, industrial and hazardous wastes generates very corrosive environments which
typically contain such corrosive constituents as SO2, HCl and sometimes HF, along with vapors/deposits
of chlorides and sulfates. The following examples demonstrate the relative improvements resulting from
upgrading to HR-160® alloy. |

1400°F (760°C) for 75 days

Thermowell in municipal waste incinerator
1800-2100°F (982-1149°C) for 180 days

HAYNES® HR-160® thermowell in a municipal waste incinerator for
170 days at 1850-1950°F (1010-1066°C)

Field testing in a chemical waste incinerator showed little scaling or metal wastage for HR-160 alloy
when exposed to the flue gas stream which contained SO2, HCl and HF for 5800 hours at 900°F (482°C)
