Wear resistant material
Wear resistant material
(OP)
Hi everyone,
We are looking for materials resistant to ash flow. We burn coal in our steam boilers, but the coal in south Brazil is not the best thing, in fact, is one of worst coal in the world. Usually we have 40% of ash. We are facing severe wear of some radial seals in our pre heater (Ljungström).
Regards

We have 2 kinds of limitations. We have to be able to screw the material on a carbon steel plate and it's preferable that it has a L shape.

The size and shape matters a lot.
Either of them is going to be light years better than mild steel.
They will need to be cast to the shape that you need.
If you want to try something that can be cut and formed you could look at a martensitic stainless steel.
These alloys can be cut, drilled, and bent when they are annealed.
Then they can be quenched and tempered to achieve fairly high hardness.
410 (0.14 %C) (make sure that you don't get the low C version, it won't harden)
420 (0.25 %C)
425 (0.55 %C)
440A (0.62 %C)
