Common Materials and characteristics of Hammer head of Hamme

1, high manganese steel hammer head
 
The high manganese steel is characterized by good toughness, good technological performance and low price. Its main feature is that the surface layer will rapidly produce work hardening under the action of greater impact or contact stress, and its work hardening index is 5 times higher than other materials, and its work hardening index is 7 times higher than that of other materials. The wear resistance has been greatly improved, but if the impact force is not large enough or the contact stress is small, the surface can not be hardened rapidly, and the wear resistance of the high manganese steel can not be fully developed.
 
The matrix structure of high manganese steel hammer is austenite and has good toughness. The hammer has good wear resistance and weak anti-beating property. It is suitable for high manganese steel hammer when the grain size is large and the price is a little cheaper. The commonly used materials include ZGMn13, which is the most widely used material in crushing machinery, which is characterized by a significant increase in the life of the hammer after cold hardening, and this austenitic microstructure is only subjected to strong impact. Under the conditions of martensite transformation and work hardening caused by extrusion, the wear resistance is higher.
 
2, high chromium alloy hammer head
 
High chromium alloy hammer wear resistance is poor, but good anti-beating, more suitable for secondary crushing, but the price is a little more expensive.
 
3, high wear resistance double alloy hammer head
 
The service life of high wear resistant double alloy hammer can reach more than 5 times of the service life of high manganese steel. The casting process is centrifugal pressure casting, which avoids the feature of inlay type easy to fall off and not wear resistant, the crushing rate can be increased by 30%, and the service life can be greatly increased.
