Counterattack plate breaking hammer is made of high chromium material. Compared with common high manganese steel hammer, it has the characteristics of high hardness, fine discharge and high wear resistance. The high hardness martensite matrix in the hammer can strongly support carbide particles, avoid the carbide falling off from the wear surface during the working process, and ensure the high wear resistance of the material. The hammer is widely used in brick factory, stone factory and other building materials industry, widely used in shale, coal gangue, river pebble, quartz stone and other minerals of fine crushing. The pulverized material has the characteristics of fine particle size and uniformity, which is recognized by customers.
