And I think at around 64 HRC the toughness of both steels become similar. So, if edge stability is a priority over everything else AEBL would be better until you hit the hardness range 63-64. Aug 7, 2021. #6. EasternShore said: Everything I am reading about Magnacut makes it seem like a dream come true, stainless, as tough as 4V if not 3V, great wear resistance etc. 4V (and Magnacut - at least on paper) vs. 3V are two different worlds when it comes to toughness. AEB L is so close to the Swedish steel Sandvik 12c27, they’re both appreciated by knife makers, they have a close chemical composition, and they share the same properties (Edge retention, corrosion resistance, hardness, toughness, wear-resistance, and ease of sharpness), and they fall in the same price range (3x45x250 mm steel bar for 10-12 Usd). AEBL-62RC O1 62rc CALMAX 60 RC N690 59rc d2 60rc ... Something I read about the new CPM Magnacut made me think that perhaps grind ability and wear resistance are not mutually exclusive and you can get good wear resistance while still having good grind ability. I seem to remember reading Magnacut performed similar in wear resistance to Elmax and. Most of these steels are carbon steels, except for CPM MagnaCut (the fancy steel cooked up specifically for knives by Dr. Thomas), which has excellent corrosion resistance. Steels like CPM MagnaCut, CPM M4, CPM 4V, and CPM CruWear fit in this category. High Edge Retention, Moderate Toughness. These steels are the good old' hard-working steels. . Pan India. Payment Mode. Online/Offline. Service Duration. 7 Days. The purpose of heat treating a knife is to harden the steel sufficiently for use. The correct degree of hardness will depend on the blade's intended purpose. It needs to be hard enough to maintain its edge yet flexible enough to endure regular and sometimes intense use. CPM MagnaCut is the result of my passion for knives and steel. I used a new approach to stainless tool steel design to eliminate chromium carbides from the microstructure. This led to a combination of properties which is better than previous stainless knife steels, and has similar toughness and edge retention to non-stainless steels like CPM.
