Erosion rate between stainless steel and carbn steel at high temperature
Erosion rate between stainless steel and carbn steel at high temperature
(OP)
Dear all,
Which one has higher erosion rate between SA-240-304H SS and SA-516-70 at 1000 degF ?

RE: Erosion rate between stainless steel and carbn steel at high temperature
High temperature erosive service, such as that found inside a coal fired boiler depends on many factors, including the hardness of the material
This is a difficult question ..... can you tell us more about what you are trying to accomplish ???

It is mixed bags that CS and SS are used for internal parts based on past experience or personal preference without a technical reasoning. So I just need to know which material can resist more erosion in high temp to standardize the material selection. It may have some relationship with hardness.
RE: Erosion rate between stainless steel and carbn steel at high temperature
At lower temp the surface of the SS work hardens considerably, at 1000F this will effect be reduced considerably.
I would suggest using steel, and in places where you are getting (or expecting) erosion using a ceramic or Co alloy overlay.

I would definitely use Cr-Mo (SA 387 Gr D plate material) at the stated conditions versus carbon steel.
