70 % NaOH storage material
(OP)
Dear colleagues,
Does anybody know's what material I can use for storage of 70 % solution of NaOH at room temperature ?
Thank you.

RE: 70 % NaOH storage material
Try the web link of Nickel development Institute(NIDI). They have large information on caustic application.
RE: 70 % NaOH storage material
SS316 would be the most suitable material for 70% NaOH at ambient temperature. For higher temperatures, Ni is the recommended material.

Temperature will determine your storage material......what temperature do you need to store the caustic without it freezing ?

Nickel (alloy 200) is very, very expensive and only useful in applications where high concentrations of caustic (>75%) are at high tempertatures ( >212F)
Good luck.....
Let us know what your final decision is...
