Simon Weedman Posted November 18, 2017 Share Posted November 18, 2017 Hi All. I RECENTLY forged a blade from 5160. The blade was annealed 3 times and then heated to 840°c for about 15 min. It was then quenched. For some reason the blade did not harden at all. The grain structure appears to be brittle. I spoke to the blade Smith who is teteaching me and he said that we may have cooked the steel. Is there any way to sort this out or should I bin it.. any advice is welcome.
