The cast grades depends to much on the product...
The problem with C-276 castings is the wide specification of certain elements. If casted well, it even survives the standard corrosion test in the "as cast condition"
Brochures of C-276 are not going to help you much, because structure and purity of the rolled material can not compared to the...
Hastelloy C22 is a further development of Hastelloy C276 for better general corrosion resistance and to handle high concentrates of chlorides better at elevated temperatures.
But as often in practice it is not that easy and there are still area’s where C276 is better than C22, in certain...
