4. Product introduction: the steel is a kind of air-cooling hardened steel, has the good toughness, hot strong sex and thermal fatigue performance. In the lower austenitic transition temperature quenching, heat treatment deformation under empty, empty quenching small generation when oxide skin tendency is lesser, and can resist molten aluminum erosion role. Commonly used in aluminum die casting die, hot extrusion dies and perforation of rods, plastic mould. In addition, also is used to make airplane, rockets resistance to 400 to 500fabrications.
