1. With good hardenability, is able to be full hardened when the diameter of cross section is under 300-400mm.
2. It can still maintain good hardness and abrasion resistance at the temperature ranging from 300 to 400℃.
3. Its toughness is better than that of Cr12.
4. Its volume changes the least in the course of quenching.
Used to manufacturing all kinds of moulds and tools with comparatively larger cross sections and complex shapes, which can bear heavy shock loads. Complex-shaped piercing dies, panel boards in the complex die mould, deep-drawing dies for steel plates, wire-drawing dies, threading screw plates, cold-extruding dies, cold-cutting scissors, circular saws, standard tools, measuring tools, etc.
