Can Alloy Steel Improve Performance of Impact Crusher?

42 crmo new hammer after quenching and tempering treatment, the microstructure of uniform distribution of tempered martensite + bainite organization, the organization gives the hammer head high hardness and toughness of the material.Material hardness, material into the depth of the material surface is shallow, cutting chip volume is small, wear-resisting performance is good.Toughness, explain material can absorb the energy of the big, not easy to formation and extension of crack, also showed a good wear resistance.

Compared with 42 crmo hammer, high manganese steel wear resistance subject to specific working conditions, to a great extent in many working conditions are difficult to form effective hardening layer. Second, it is because of the wear resistance of high manganese steel hammer is subject to conditions, so the hammer in your work performance is not stable.Formed by the large stress enough hardening layer, the small amount of wear and tear and wear resistance;On the other hand, the large amount of wear, wear resistance is low.And 42 crmo hammer head of the organization for the stability of the mechanical properties of good tempered martensite, no phase change in the process of friction and wear, so its wear resistance than the traditional high manganese steel hammer, and show there has been a steady performance, therefore, can improve the work performance of counterattack crusher.

The hammer head of impact crushing machine is the key of vulnerable parts, so the material quantity is bigger.At present, the domestic many manufacturers of most of the hammer crusher with high manganese steel material, the material with high manganese steel hammer head under many conditions are difficult to form effective hardening layer, wear resistance is not good, service life is too short, which seriously affect the working performance of a hammer crusher.And 42 crmo alloy steel new hammer head, in the actual production than the wear resistance of high manganese steel...
