Jul 15, 2019 You can see that for a 4% vanadium steel, the VC content is reduced from ~8% in a low chromium steel down to only 2.5% VC in a 20% Cr steel. Instead the vanadium contributes to a larger amount of chromium carbide and in fact partially replaces the Cr with V, making a complex (Cr,V) 7 C 3 carbide of higher hardness than the plain Cr 7 C 3 .
Jun 29, 2017 Tungsten Carbide is 72 Rockwell C. Vanadium Carbide is 82. Conventional smelting only allows 2-3% Vanadium alloys. Particle metallurgy allows up to 15% Vanadium in steel. More Vanadium at the higher Rockwell is a no brainer for wear resistance.
Nov 21, 2019 (8) Vanadium addition in Martensitic steel can increase the tempering and softening properties of the steel, so that the steel can maintain the shape of Martensitic slab in the tempering process, or release vanadium carbide in the tempering process, resulting in secondary hardening effect.

Oct 10, 2018 Tool steel refers to a variety of carbon and alloy steels that are particularly when used for cutting and drilling. The four major alloying elements that form carbides in tool steel are: tungsten, chromium, vanadium and molybdenum. The two materials from which most cutting tools are made are carbide and high speed steel (HSS).
Apr 13, 2020 Another fact known is that a reduced carbon and vanadium content would lead to a steel that was tougher and easier to grind because of a reduction in overall carbide content. This is why 3% vanadium 3V has much better toughness and grindability than the 10% vanadium 10V, though at the cost of wear resistance.
