Need suitable MOC for ammonium chloride at high temp
2004
ACRONYMS:
MOC = material of construction
Q. We are manufacturing Ammonium chloride by evaporation process of Ammonium chloride solution -25%, in S.S Pan by direct firing of wood. We have used SS316L & SS316 as MOC but both the metal pans get cracks within 7-10 days without giving much production due to chloride stress. Kindly advise which MOC is suitable for this product at high temperature of 800-900 °C by direct wood firing.
Your early reply is appreciated.

A. You could try Duplex steels, However the confirmed MOC is either Hastelloy or Titanium.
