Chrome plate thermal expansion question.




I am considering hard chrome plating as a fix for abrasion wear inside 2" dia. SS304 pipes at 950F process temperature. Will there be any tendency of the chrome plate to peel off after several thermal cycles?

Chrome plate becomes softer as it is heated. At the temperature you want to go to 950 °F the chromium would have a hardness of less than 500 HK100.

If you still want to plate you should evaluate electroless nickel. Electroless nickel becomes harder with an increase in temperature.

I'm not sure about this. Could type 409 stainless steel pipes, mirror polished (600 grits) be the solution?

Would be interested in hearing other opinions.

You could try 2205 or other Duplex grade stainless tube.
