I have a setup where nichrome heating element will be in contact with steam. Can it react with hot steam at 900 C? if it does, I can encase it in something like iron/stainless steel etc. If it doesn't i can use it directly.

From wikipedia: Nichrome wire, when heated to red-hot temperatures, develops an outer layer of chromium oxide. So reactions need to be assessed with chromium oxide.

I am using this as a supplemental heating because electricity is intermittent in my area. Also expensive. Will switch to solar thermal soon.

Appreciate the assistance.

Oxidation in steam is about the same as air so steam itself will not make a difference in life. However, are there any minerals in the steam ? A salt like sodium sulfate may cause "hot corrosion".

  • $\begingroup$ That is getting near the top of the temperature range for long life with nichrome. $\endgroup$ Commented Dec 25, 2022 at 16:40
