While back I made some 454-350 noes. I was obviously off in my alloying attempt, they turned out 7-8bhn. Had hopes of 9-10bhn air cooled. I went ahead & heat treated them for an hour at 415. A week later they test about 7. This is a bit perplexing. The alloy has some lino/ww. The 356-95 were 9bhn air cooled & heat treated at the same time, they are now about 18bhn.
Clearly missed the mark on alloy, but thought they should have hardened some. Why didnt they harden at all? With some antimony & at least a trace of arsenic, I would have guessed for 10-12bhn, instead it seems I annealed them.
Any thoughts or experience welcomed.
