Nov 25, 2019· In general, 440A has excellent hardening performance and high hardness, and its toughness is higher than that of 440B and 440C. 440B has a higher hardness and toughness than 440A and 440C for cutting tools, measuring tools, bearings and valves.440A vs 440C BladeForumsOct 14, 2011· To be clear, 440A is a solid knife steel and in fact has several advantages over 440C; it is tougher, has a higher edge stability (much), and is more corrosion resistant. But in practice it tends to be used on cheap knives and gets low end heat treatment and thus the performance is often very low.440A vs 440C vs other choices for knife FinishingJun 12, 2009· A. John, I'd consider the corrosion resistance of 440A and 440C to be so close as to be equal. The difference between these two grades is in hardness and ductility, due to the higher carbon content of the 440C.
