Sodium.nitrate and.potassium nitrate salts
(OP)
Hi guys I want to know what metals I can use for heating a 60_40 mix of sodium and potassium nitrates .
What will not react with this is mix?
Thanks

What is your application?

Metallic materials aren't going to be a good choice for a molten chloride bath.
RE: Sodium.nitrate and.potassium nitrate salts
As long as the Cl impurities are kept low (low ppm levels) there are many alloys that work. These salts are used in some of the solar thermal power plants.

If I had a 44 gallon drum of 60/40 (using it as an example)sodium/potasium nitrate heated to 600 deg celcius how do I work out how much energy is stored in it? Need it to recover heat to boil water for.steam.cleaning and a couple of other applications as well
RE: Sodium.nitrate and.potassium nitrate salts
Look up the heat capacity of the molten salt and based on the volume of salt convert to mass you can calculate the heat absorbed. You better be sure you understand the safety implications of handling this stuff.

Too hot is very dangerous with this stuff as EdStainless has indicated.
Again, I have nothing to recommend to you for a metallic material for use in contact with molten chloride salts capable of > 800 C temperatures. The nitrate/nitrite mixtures are NOT capable of those temperatures- they will blow up.

Should I trust the info on wiki?
There seems to be quite abit there.
Thanks guys

Couple of questions
how.much does the sodium/potasium mix expand when heated? 20-30%
Does pressure increase the "boiling" point of these chemicals? I suspect not
Appeciate the help guys
