What distinguishes HR-160
Gas composition matters as well as temperature in hot-service materials. HR-160 illustrates this distinction: nickel, cobalt, chromium and silicon contribute to resistance in sulphur-bearing hot environments, making corrosive combustion gases a characteristic duty.
Hot corrosion and oxidation
Oxidation describes reaction with oxygen, while sulphur-bearing gases and other constituents can cause different surface effects. HR-160 is used in these more complex hot-corrosion environments, extending its role beyond oxidation resistance in air.
Incineration and heat recovery
Typical uses include waste incinerators, recuperators and heat exchangers, as well as hot-gas ducts and thermocouple protection tubes. Recovery boilers and some cement-kiln components are further examples where gas chemistry accompanies heat.
A separate grade from HR-120
HR-160 is not an alternative spelling of HR-120. Its cobalt- and silicon-bearing composition gives it a distinct hot-environment profile. It is identified by 2.4880 and N12160, despite applications overlapping those of other furnace alloys.
Typical application areas
Waste incinerators, recuperators, heat exchangers and hot-gas ducts.
