Serving the high temperature heat processing industry since 1979 !
Industry standards were established for heat resistant alloy castings before my birth (1954). At the bottom of the page is a short list of the most common heat resistant alloys. The comprehensive list of alloys can be found here.
Foundries (including Alcon) develop their own names/recipies for alloys. They will tweak the recipe then add some wiz dust and call it propritary.
A foundry should tell you the key recipe ingredients (i.e. 35Nickle/15Chrome, aka HT). Why would you buy a material you know nothing about?
A foundry should put it in writing, or at least tell you! LET THE BUYER BEWARE!
If you do not recognize an alloy designatioon quoted to you and cannot find an industry standard, HOW DO YOU KNOW WHAT YOU ARE BUYING? CAUTION!
Why have premature failure if the metallurgical recipe is NOT industry standard AND ONE THAT HAS STOOD THE TEST OF TIME? Call me if you wish to discuss this!
This is what a transparent alloy leader will offer you Would you like a copy of this?
