Reactor selection
Thread Content
I’d like to ask everyone: what materials can resist corrosion by sulfuric acid and sodium hydroxide at around 180°C and 1 MPa, for use in hydrothermal reaction reactors?
Hastelloy 276? Is it corrosion-resistant?
At these temperatures and pressures, neither titanium alloys nor Hastelloy can withstand the corrosion caused by sodium hydroxide and sulfuric acid; NS142 can handle it, so try using it with test pieces first!
Which is better, ns142 or no8825? Can no8825 be used?
Ns142 and 825 differ only in standards and naming conventions.

How to answer without a concentration value? All the answers are jokes~~~~~
Incoloy 825 (for use at 550°C in acidic or alkaline environments), Incoloy 625 (for use at 450°C in acidic or alkaline environments), Zeron100, and CD-4M Cu are all viable options; Zeron100 and CD-4M Cu can be used at lower temperatures.
