It is a high-strength medium carbon steel, with low cold deformation plasticity, welding performance and poor hardenability, but no tempering brittleness, and the cutting performance is acceptable. It is generally used under normalizing or quenching and tempering for the manufacture of machining parts and spring parts with high wear resistance requirements and little dynamic load and impact effect, such as forged gears, tie rods, rolls, shafts, friction discs, agricultural excavation ploughshares, heavy-duty mandrels, etc.
