Alloy for hot chlorine service

[StoneCold]

I need an alloy option for a 400C dry chlorine service. Pressure is low <50 psig. Application is as a melting tank and reactor for a molten metal reaction. Reactor design temperature is probably 450C or better.
Any ideas. The reactor is small maybe 10 gallons so exotic alloys are acceptable.

What type of molten metal????

Reactor design temperature is probably 450C or better.

Need a maximum reactor temperature for design. ...Or better... does not cut it.

Not to be coy but the metal is from the same family as lead, and has similar characteristics. So it is not a sodium or lithium type metal.

Design temperature is 450 deg C.

Once the reactor metalurgy is determined the next challange will be how do you valve off a molten metal at the bottom of the reactor to get small quantities out of the reactor???

Valves that use a tapered plug that rises and falls might be best.
Picking an alloy to handle the metal will be the trick.
If this is really dry, like -80C dew point dry, then you don't have much concern for regular corrosion mechanisms. Just make sure that it never gets exposed to the air.
