13949000083 Although Hypoeutectic Hammerhead Hammerhead is considered to be excellent, but in the harsh working conditions of wear, life is quite short. And hypoeutectic hammer compared to the carbon content of the hammer and hypereutectic high chromium volume, clearly showing the volume fraction of carbides, can promote improved hammer wear. But appeared in hypereutectic hammer in a coarse primary carbides, resulting in a sharp decline in the toughness of the hammer, the casting and heat treatment process easy to crack, so that the hammer reject rate increases, the current application of hypereutectic even hammerhead less. But with too refined and improved toughness hammer eutectic carbides in the future will continue to expand the scope of application.
