need plate for temperature up to 2100F

Hi, I need to built a special part for a customer and this part need to resist to temperature up to 2100F. We have no other stress than temprature stress (around 500 psi internal stress)

Do you have any idea ?

Is 2100F the temperature for the plate or the air temp that it'll be in?

Does this have metallic? If not, take a look at ceramics.

2100F is on the outer reaches of my experience. Corrosion/oxidation is going to be a big problem if your atmosphere is anything but inert.

I can think of three materials at least worth a look:

- Nickels - Ceramics - Refractory metals (columbium, aka niobium) with disilicide coating

How about tungsten?

Molybdenum Silicide, MoSi2 Notes: MoSi2 is often used as a heating element in high temperature furnaces. It has an appropriate resistivity and is stable toward oxidation up to

1600°C because a coating of SiO2 forms. Maximum Service Temperature, Air 1600 °C 2910 °F [Matweb]

Ceramic; Alpha alumina, Al2O3, aluminum oxide, corundum, aluminium oxide Maximum Service Temperature, Air 1750 °C 3180 °F No Load [Matweb]

I just picked two out to get you into search mode

You could also consider another ceramic: silicon carbide (SiC) which could do the trick at this temperature.

See:

for instance.

Good luck!

Have a look into Iron-Aluminides

They are cheap, formable/castable/cuttable, and take a lot of thermal cycling.

Typical applications inlude heat treating ovens.

It's the temperature that my customer take at the surface of his pipe... (stainless steel 304) but I said to him that I'm not sure that is correct to use ss304 up to 1200C (or 2100F in fact 1200C = 2192F)

Dear Yves Rossignol:

You are correct. The stainless steel will have some major changes in chemical properties above 800 deg F, and will be entirely useless above

1800 deg F or so. Thermal cycling will make it fail any reasonable challenge after just a few cycles.

Inconel would be a better high temperature metal and pipes are made from it. So take a look at it.

good to 1500 deg F.

If the pipe contains moving fluids at much less than 2100 deg F, then one could consider a coating (which will require maintenance). URL:

Thanks, but how about letting the OP do some work here. ;)
