H 120 casting
H 120 casting
(OP)
I have been asked to develop IGT heat shield castings in alloy H120. I have no experience with this material. I shall be thankful,if I am given a few tips regarding its castability,properties and any common reasons for rejections. Thanks all for your help.





RE: H 120 casting
Can you provide more information on this alloy? When you mentioned heat shield castings, my first thought was the alloy HR-120 by Haynes.
RE: H 120 casting
After I had exhausted all resources available I very hesitatingly posted this question. (Scared to be labelled Moron of the day).
I have also asked the buyer/enduser to provide details. I hope he does it soon. This RFQ was generated from US and I hope he does not consider me a Moron once again!!(for having revealed my ignorance)
RE: H 120 casting
I am reproducing the extract of a communication that I just received. Can you please offer your comments now on this alloy casting
It is Ni-33Fe-25Cr, UNS No. N08120 Max Temp 900-degree C, Data Max 930-degree C This alloy is referenced in high temperature Ni Base Alloys. I have seen references to the “H120” in UK literature, but it was listed as a wrought alloy for flooring, decking, etc.
RE: H 120 casting
As I suspected, the material is similar to Haynes HR-120

RE: H 120 casting
I have made heat treatment castings parts in this alloy. But I was not aware of this designation.Thanks once again.
