This is a nickel-molybdenum alloy that is particularly suited to handling reducing acids at high concentrations and temperatures.
It may be used in the as-welded condition since it is not susceptible to grain-boundary carbide precipitation following welding.
The alloy should not be used in the presence of oxidizing media.

Application
This alloy finds its main uses in the chemical manufacturing industries, particularly in the production of acetic acid, herbicides, insecticides, ethylene glycol and ethyl benzene. It is also used in the production of high-octane gasoline.
WELDABILITY
This alloy may be welded by the gas-metal-arc, gas-tungsten-arc and shielded-metal-arc processes. Parts may normally be used in the as-welded condition, but a post-weld anneal will result in optimum corrosion resistance.
