All "newbies" / beginners, please post your questions in this forum. In general, I didn’t change the austenitizing temperature much when comparing the same steel at different hardness so the trend of hardness vs edge retention looks about right for steels like S30V and 10V. Admital does not, and NEVER has carried any L-6. 12.4k posts [Picture Hvy] Some of my Orishigane for Japanese Blades. 8670 is essentially 1070 steel with additional chromium and nickel. This is an L6 steel variant . It’s not shallow hardening enough to form a true hamon, but it’ll print a line, as will L6. So that austenitize-temper decision can affect the final properties in terms of toughness and edge retention even when at the same hardness. Even though it supports DirectX 12, the feature level is only … Click a specific steel below to see its elements. According to the chemical composition and the HRC of the steel, the 14c28n Steel has the following features: 14c28n Edge Retention: 14c28n Steel offers good edge retention with a maximum hardness of 62Hrc, and the mixture of Chromium and Carbon.

Hover over an element to learn more about how it affects steel performance characteristics. 80CrV2 is also a high-carbon tool steel that is ideal for tough knives. It’s reasonably similar to L6, and it’ll take a temper line. NOTE: s35V steel, even with Hot Enhancement will break under the stress of extreme lateral force. It has better edge holding than 1095 with twice the toughness. What they do sell is a 8670M with only half the alloy amounts of L6.
