ALLOY601 is a solid solution strengthened Ni-Cr-Fe alloy with additions of Al + Ti

  • outstanding resistance to oxidation at high temperatures
  • good resistance to carburizing conditions
  • good mechanical properties at both room and elevated temperatures
  • good resistance to stress-corrosion cracking

Alloy 601 is specifically recommended for service above 550 °C (1022 °F) because of higher creep-rupture properties, resulting from controlled carbon content and coarse grain size.

Corrosion resistance

ALLOY 600 is a heat resistant alloy on account of its excellent resistance above 550 °C (1022 °F) against hot gases and combustion products, as well as against molten salt and molten metal corrosion, while at the same time exhibiting good mechanical short-time and long-term properties. Even under severe conditions, such as under cyclic heating and cooling, Alloy 601 retains a tightly adherent oxide layer which is very resistant to spalling.
Resistance to carburization is good. Alloy 601 has also shown good resistance in carbonitriding conditions, if a sufficiently high oxygen partial pressure is present.


ALLOY601 has found a wide variety of applications in industries as diverse as thermal and chemical processing, pollution control and power generation.

Typical applications are:
  • trays, baskets and fixtures for heat treatment plant
  • refractory anchors, strand-annealing and radiant heater tubes, high-velocity gas burners, wire mesh belts in industrial furnaces
  • insulating cans in ammonia reformers and catalyst support grids in nitric acid production
  • components in exhaust gas systems
  • combustion chambers in solid waste incinerators
  • tube supports and ash-handling components
  • components of waste-gas detoxification systems
  • oxygen preheaters
