Performance and use
Hot formed chromium-molybdenum alloy steel that maintains high wear resistance and heat resistance at high temperatures. Very good hardenability. Used as extrusion dies for light alloys such as mandrels, pressure washers, manifolds, self-centering rolls, shear rolls, dies, and liners. Also suitable for injection moulds, bars and drawers for light alloy machining. Dies, inserts, punches and mandrels for forging presses, as well as dies and punches for making bolts, nuts and rivets. RDC 2V is also suitable for plastic mold making. Particularly suitable for liquid nitriding (Tenifer treatment) and can be water cooled. Recommended preheating temperature for hot work tooling: 250-350°C.
RDC 2V (Multibloc HQ) is a product of ESR (electroslag remelting) and Micro900BG process (our special forging and heat treatment process), which gives the product a very high impact resistance and non-directionality, as well as very high mechanical and physical properties. Uniformity. In addition, the very high purity makes the steel extremely polished.
The MICRO 900/BG structure has been additionally microstructured to form an extremely homogeneous soft annealed microstructure without grain boundary carbides. It meets the strict requirements of VDG Merkblatt M82 (German Association of Foundry Specialists M82) for commonly used cores and even meets the requirements of DGM (German Materials Association) for cross-sections up to 500 mm (e.g. 1.2344), which greatly increases the strength.
