The copper brittleness defects control of BP440 bulletproof steel plate

SKD5 use: commonly used die-casting die steel. SKD5 steel has low carbon content, high toughness and good thermal conductivity. At the same time, it contains more carbide forming elements chromium, tungsten, and vanadium. The phase transition temperature is increased, so that the steel has high high temperature strength, hardness and good thermal conductivity. Thermal fatigue resistance; hardening. Suitable for manufacturing high temperature, high stress, but not impact load, die-casting copper, aluminum, hot top forging die, convex and concave dies, inserts, etc. of flat forging machines.

DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel BP440 bulletproof steel plate is widely used in punching die, cold work forming die, cold drawing die; forming roll, punch; precision stamping die; precision cutting die for wire cutting and punching die for various purposes; difficult to process materials Tools for plastic deformation; cold forging, deep drawing and thread rolling dies; high-speed punching punches, stainless steel punches.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel BP440 bulletproof steel plate produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
