DIN 1.3243 steel is a tungsten-molybdenum series general cobalt-containing high-speed steel, which has improved red hardness and high-temperature hardness, improved wear resistance, and good cutting performance, but the strength and impact toughness is low, and it is easy to oxidize and decarburize. It is generally used as gear cutters, milling tools, punches, cutter heads, and other tools to cut hard materials.

DIN 1.3243 steel is a cobalt-containing high-speed steel with high red hardness and wear resistance, suitable for cutting hard materials. It is widely used in the automotive, aerospace, mold manufacturing and shipbuilding fields.

After heat treatment, it is necessary to pay attention to the release of residual stress, and surface hardening technology can improve performance. The chemical composition includes elements such as carbon and silicon, and the mechanical properties are good.
