Re: Narex heat-treatment process

Patrick Chase
I don't think that 420HC would be a very good candidate for austempering - it usually works best with higher-C and higher peak hardness. Also I don't see any references to salt baths or interrupted quenches in their literature.

It looks to me as though whatever Buck did was more about wringing additional wear resistance out of a fundamentally soft steel than about boosting toughness of an amply hard one like Narex. One possibility is that they did something to promote carbide formation, in which case your sharpening issues may result from Chromium carbides, which are a lot harder than SiO2.

I wouldn't expect you to have much "real" trouble sharpening an austempered low-alloy steel such as Narex uses, as you just need to be careful about the wire edge.
