Company Evek GmbH offers to buy a tube, a circle, a bar of chromium-molybdenum vanadium steel 30Х3МФ, 31CrMoV9, 1.8519. The price — from the manufacturer. Supplier guarantees strict adherence to the range of products supplied, as well as its delivery to the point set by the buyer.
Application
These steels are well suited for hot forging at temperatures between 850 and 10500 C. Workability by cutting is medium, it is necessary to use tungsten carbide tools. Weldability of steels is limited, with the use of welding fluxes or under a layer of inert gas. Pipes of these steel grades are used for mounting and laying pipelines that transfer hot liquids and gases.
