With the upgrading of the construction industry, building materials, may also need to tie it to upgrade. Common hammer crusher wear also need to increase, then how can strengthen its wear it? In general, the greater the hammer hardness are greater wear resistance. To improve the wear resistance of the hammer, it is necessary to increase its hardness wear-resistant high chrome hammer price, but with improved hardness wear-resistant high chrome hammer price, hammer impact toughness is reduced. So the question is, how to balance the hammer suitable hardness and good impact toughness is the key to improve the wear resistance of the hammer. Hammerhead commonly used materials are: high manganese steel, high chromium cast iron, carbon steel. High manganese steel toughness, good technology, low price, its main feature is the role of the larger impact or contact stress abrasion resistant high chrome hammer characteristics, the surface layer will quickly produce work hardening, work hardening exponent than the other materials with high 5-7 times, greatly improved wear resistance. But if the impact is not enough to use towel or small contact stress, do not make the surface rapidly produce wear work hardening, high manganese steel can not be fully realized. However, the complexity of its manufacturing process, process requirements more stringent. Mainly for low-carbon steel alloy structural steels containing chromium, molybdenum and other kinds of elements, high hardness, good toughness, the matrix organization martensite, bainite or bainite and martensite composite tissue. Hammer hardness of about HRC 45, toughness d. ≥15 J / resistance. Under the same operating conditions, the service life of at least more than the high manganese steel hammer I fold increase. But the hammer is a key transfer of heat treatment, quenching and heat treatment requires not only the overall tensile strength up to 850 MPa or more, and require considerable plasticity and toughness.
