Alloy 600/600 H Applications
Typical applications for Alloy 600 and 600 H are:
- Transport rollers, steel pipes, ventilators and other installations in industrial furnaces.
- Industrial furnace muffles, in particular for heat treatment in N2 atmospheres.
- Thermal element protective conduits in nitriding and carburizing atmospheres.
- Pipes for dichloroethylene pyrolysis.
- Components in the production of uranium tetrafluoride from hydrofluoric acid.
- Production of caustic alkalis, especially with the presence of sulphur bonds.
- Reaction vessels and heat exchanger pipes in the production of vinyl chloride.
- Plant parts for the production of chlorinated and fluorinated hydrocarbons.
- Parts such as cladding tubes for control rods, reactor tanks and seals, steam dryers and separators in boiling
- Pipes in TiCl4 evaporators in the production of TiO2.
- For the automotive industry the alloy is used for high temperature sensors, rupture discs in airbag systems,
electrodes for spark plugs and gaskets.
- Vessels and piping used to contain caustic solutions.
Alloy 600 and the solution-annealed variant 600 H are nickel-chromium-iron alloys.
They are characterized by:
- Good resistance against oxidation, carbonization and nitriding
- Good resistance to stress corrosion in room and increased temperatures.
- Good resistance against dry chlorine and hydrogen chloride.
- Good mechanical properties at both low and high temperatures.

Welding Alloy 600/600 H
Alloy 600 and Alloy 600 H can be welded using the customary and conventional arc techniques such as TIG
or MIG impulse technology. The material should be in its annealed condition for welding. A low heat input and fast heat
removal must be ensured. The maximum interpass temperature should be between 100 and 150 °C (212 and 302 °F).
Usually neither pre-heating nor a subsequent heat treatment is necessary.
The generally applicable safety recommendations, especially for avoiding dust and smoke exposure must be observed.
