I also have a better unerstanding wht the part I'm analysing...
Thanks Arunmrao and EdStainless for the good replies!
The foundry has an AOD converter and the carbon content is very low.
Why is the low carbon content and high Cr content a problem from a metallurgical point of view (high melting temp, viscosity...)?
Thanks for the casting process input and...
