What is the corrosion behavior of calcium hydroxide solution when in contact with 316L at around 80°C? I think it shouldn’t corrode. There is a request for assistance with the process of producing acetylene through calcium carbide electrolysis.
You can take a look at the corrosivity comparison table. There should be no problem. However, high temperatures can have an impact.

However, the acetylene gas produced by the hydrolysis of calcium carbide sometimes contains impurities such as hydrogen sulfide and phosphine; especially hydrogen sulfide, which can have a slight adverse effect.
