Multimet N155 alloy is utilize in applications which engages high pressure at up to 1500°F temperature, and medium pressure up to 2000°F. It offers exceptional oxidation resistance, good flexibility, and can be easily manufactured. Its high-temperature properties are built-in and doesn’t dependent upon age-hardening treatment.

It can been utilize for various aircraft applications which includes of afterburner parts, combustion chambers, exhaust manifolds, turbine blades, tailpipes and tail cones.

It can also be exceptionally used for high-temperature conditions and it has been certified as economical material for constructional use in heat-treating tools where strength at higher temperatures are crucial.

It gives good resistance to corrosion in definite means under both oxidizing and reducing environment. When it is been solution heat treated it gives the same resistance to nitric acid as stainless steel. It provides better resistance compared to stainless steel in hydrochloric acids environment. It tolerates all applications of sulfuric acid at room temperature.

UNS R30155 material can be machined, forged and cold-formed by standard process methods. It can be welded by various bending and resistance-welding methods.

It is supplied in the solution heat-treated condition to get guaranteed prime properties.

Multimet N155 alloy sheet is been solution heat-treated at 2150°F, temperature. For a period of time dependent upon the thickness, accompanied by a quick air cool or water quench.

UNS R30155 Rod Bar stock and plate i.e. in 1/4 in. or heavier than that are frequently solution heat treated at 2150°F, temperature accompanied by water quench.

Multimet N155 Applications

It can utilize in various industries because of its outstanding mechanical and corrosion resistance properties. Some of its prime applications in industries includes the following:

  • Aerospace Industries: It is utilize in aircraft engine elements such as exhaust system, turbine blades and burners.
  • Chemical Industries: It is utilize for chemical processing tools such as heat exchangers, reactors and valves.
  • Nuclear Industries: It is utilize in nuclear power industries for reactor elements like, fuel sheathing, and pressure vessels applications.
