If added in small amounts, it only has little impact. In tungsten-containing tool steel, addition of cobalt also promotes martensite formation.Ĭobalt is generally not added to cast iron. Since cobalt increases the melt temperature and therefore allows for utilization of higher solution heat treatment temperatures, a large proportion of carbides is dissolved during annealing and diffused during tempering. These kinds of steels are used for production of tools for machining of hard materials. Two frequently used types of tungsten-containing high-speed steels contain between 5 and 10 %, sometimes even 15 % Co. Stabilization prevents decarburization during hot forming and eliminates problems during machining of steel with more than 5 % Co.Ĭobalt is an important constituent in tungsten-containing tool steel since it imparts the required hot hardness to those kinds of steels and thus increases their cutting performance at high temperatures. Cobalt-containing steel is often stabilized by addition of chromium, which forms complex carbides. Carbide, Carbide former) and is predomiantly present in steel in the form of non-resistant carbide Co 3C. It imparts corrosion and wear resistance to steel and leads to increase of tensile strength and yield strength but reduces toughness.Ĭobalt displays a tendency towards carbide formation, similar to iron (s. For this reason, steels with poor hardness penetration capacities contain up to 1 % Co.Ĭobalt hardens ferrite and significantly adds to its hot hardness. Hardness penetration capacity) during quenching. In contrast to most other alloying elements, cobalt reduces the hardness penetration depth (s.a. Cobalt increases the resistance of austenite in high-alloy steels during quenching from high temperatures. γ iron and cobalt are soluble within each other under any conditions and in any ratios solubility of cobalt in α iron is up to 75 %.Īddition of cobalt increases the solidus temperature of steel, lowers the A point and extends the region of the γ phase. The other, the cubic face-centered type, exists above this temperature. Cobalt is the main component for special cobalt alloys, that are partly used for investment casting products.Ĭobalt is available in two modification variants, one of which is the hexagonal close sphere packing and is resistant below 450 ☌. Moreover, cobalt is an alloying element in martensite hardenable die steels, heating conductor materials and creep-resistant high-temperature materials. Materials for permanent magnets, high-speed steels and hot-work steels are alloyed using cobalt. coefficient for linear expansion Coefficient for linear expansion High-melting, steel gray lustre heavy metal that provides similar properties as nickel in many aspects.
