W9Mo3Cr4V High-Speed Steel delivery status

Hot-rolled, forged, and cold-drawn steel bars are delivered in an annealed condition, and hot-rolled, forged steel bars are processed by annealing and other processing methods (peeling, light drawing, polishing, polishing, etc.).

W9Mo3Cr4V steel is easy to smelt, and it has good heat and cold plasticity, high yield, and the carbide distribution characteristics are better than W18, similar to M2, the decarburization sensitivity is lower than M2, and the production cost is lower than W18 and M2.
