Serving the high temperature heat processing industry since 1979 !
Industry standards were set up for heat resistant alloy castings before I was born. There is a short list of common heat resistant cast alloy standards at the bottom of this page. A comprehensive list of alloys can be found here. Some foundries will develop their own nomenclature for their alloys. They will tweak the recipe then add some wiz dust. This is all well and good. Some cast alloy names have been trade marked ((i.e., Supertherm (Duraloy), NC11 (Alloy Engineering and Casting)).... A foundry will tell you the key recipe ingredients (i.e. 35/15...), and they will put it in writing. LET THE BUYER BEWARE! If you do not recognize the alloy name and cannot find an industry standard, HOW DO YOU KNOW WHAT YOU ARE BUYING? GET IT IN WRITING!!! Why have premature failure if the Nickel and Chrome content are not the same? If you want discuss this with me, It would be my pleasure!
This is what a transparent alloy leader will offer you Would you like a copy of this?
