M390 steel composition. Known for its exceptional edge retention, corrosion Thanks to its superior composition—rich in chromium, molybdenum, vanadium, and tungsten—M390 maintains a razor-sharp edge even after prolonged use and harsh conditions. This steel features a unique design that aims to reduce the Chromium in its composition, in order to dissolve the available chromium carbides during heat treatment. 5% vanadium carbides) delivers exceptional edge retention that surpasses many competing steels. . Jul 17, 2025 · CPM MagnaCut steel is the idea of Larrin Thomas, a renowned steel author but produced by Crucible Industries in 2021. Mar 30, 2020 · The composition of the steel has a much greater affect on carbide size than the powder metallurgy manufacturing technology. Apr 6, 2023 · M390 steel is a high-performance, high wear and tear resistance steel. But why? Knivesandtools explains! Its toughness significantly exceeds that of S35VN, 20CV, M390, CPM-154, and similar PM stainless steels, owing to a finer carbide structure consisting primarily of small vanadium and niobium carbides, with no chromium carbides when properly heat treated. May 13, 2025 · Here, we will explain what M390 Steel is in detail by talking about its composition, properties, equivalent, price, applications, and differences with Magnacut steel! BÖHLER M390 MICROCLEAN is a corrosion-resistant, martensitic chromium steel produced by powder metallurgy. Feb 17, 2026 · Check out our essential guide to knife steel as we discuss the most popular steels and the key factors to consider in choosing the best steel for your knife. The primary alloying elements in M390 include chromium (Cr), molybdenum (Mo), vanadium (V), and carbon (C), each contributing significantly to its overall characteristics. 20CV, MagnaCut, Elmax & more. Apr 27, 2019 · M390 Properties Hardness Bohler specifications of the M390 stainless steel specifies that this steel hardens and tempers to a Rockwell hardness of 60-62HRC. As shown the composition of M390 steel includes a lot of materials, which demonstrate the power of an M390 steel knife, it guarantees toughness, resistance and strength, it will be a great choice for hunting, camping or any outdoor usage. 9%), giving it a unique edge over other steels. M390’s approximately 22% carbide volume (18% chromium carbides + 2. You do not have to worry about the surface of your M390 knife getting destroyed or chipped away easily.

This is a considerably high hardness level and provides a perfect balance between toughness, wear resistance, and great edge retention. Dec 6, 2025 · Is M390 the best knife steel? Discover its composition, performance, pros & cons, and how it stacks up vs. The vacuum hardening process guarantees a uniform steel structure, excellent dimensional stability, and increased wear resistance. Discover M390 steel's properties as a knife material in this article. The oxygen content was confirmed to be reduced in Bohler-Uddeholm steels relative to Crucible and Carpenter, but a resulting reduction in toughness was not seen in testing. 3 hours ago · The component is made of 440C stainless steel, vacuum-hardened to 56–58 HRC. As a result, manufacturers have incorporated this high-performance steel into various folding knife designs tailored for everyday carry, tactical operations, survival scenarios, and multi-functional utility. Thanks to this, the pivot offers long-lasting durability and retains its properties even under intensive use. Oct 19, 2021 · Steel Metallurgist Larrin Thomas uses tests of knife steels to rate the steels and explains the factors that control performance. Due to its alloy design, this steel has very high wear resistance and good corrosion resistance. This composition delivers outstanding corrosion resistance, edge retention, and wear resistance—qualities that define a super steel. rlwy dds orae tesx bkbdg vqwvnymd wyq kvmeif rabph hfwdz
