The wear-resistant alloy hammers produced by Hebei Zhuxin Wear resistant Materials Co., Ltd. include bimetal composite materials, alloyed ultra-high manganese, alloyed high manganese steel inlaid with tungsten titanium alloy, alloyed ultra-high manganese/high manganese steel, high chromium cast iron and other materials.
The head of the hammer is made of medium carbon medium chromium alloy steel as the base material and then inlaid with Cr20 high chromium alloy cast iron rod (with a diameter of 10-15mm). This is not recommended. The combination of medium carbon medium chromium alloy steel and Cr20 will not have good toughness and wear resistance, low cost and low cost. One of the more mature methods is to inlay high manganese steel matrix with cemented carbide rod, which has high impact toughness and good wear resistance. Then there is the 40CrMo or 40 # steel handle composite high chromium hammer head, which has good wear resistance and high cost performance.
The hammer head of crusher specially used for crushing coal gangue is made of high chromium composite material; The working face of the hammer head of the crusher is made of high chromium materials with high wear resistance, such as Cr20, Cr26, etc. The hammer handle is made of carbon steel. The combination of the two materials for the hammer head of professional coal gangue crushing not only achieves wear resistance, but also saves costs.
In addition to the crusher hammers specially used to crush coal gangue, there are also hammers specially used to crush the following materials: limestone, quartz stone, granite, river pebble, bluestone, sandstone, etc; What kind of materials should be crushed with hammers made of special materials for better results
[Common alias]: high manganese steel hammer head, bimetal hammer head, composite hammer head, large metal tooth hammer head, medium chromium alloy hammer head, hard alloy hammer head, etc
[Applicable equipment]: hammer crusher, hammer crusher
[Main materials]: high manganese steel, modified high manganese steel, ultra-high manganese steel, modified high manganese steel, alloy steel, bimetal composite, composite materials, high chromium materials, ultra-high chromium cast iron, multi-element alloy steel, high and low chromium cast iron, high-quality high manganese steel

Which material is more wear-resistant?
The wear resistance of high chromium alloy hammers is relatively better, but the toughness of pure high chromium hammers is poorer. Bimetal high chromium composite hammers are compounded by special pouring process. The handle is made of multi-element alloy steel with good toughness, and the working part is high chromium alloy (Rockwell hardness reaches 61-63). Under the premise of ensuring wear resistance, the problem of insufficient toughness is solved. It is recommended to use a bimetal composite hammer head.
Different working conditions are suitable for different hammers. It is not allowed to say in general which hammer material is wear-resistant. Each material of crusher hammer has its own scope of application. For example, the alloyed high manganese steel hammers, ultra-high manganese steel hammers and inlaid hard alloy hammers of Hebei Zhuxin Company are suitable for hammers with material impact greater than 400mm. The greater the impact, the better the work hardening performance of high manganese steel material, and the more advantages of high manganese steel can be brought into play. In particular, the cemented carbide big hammer head is inlaid with tungsten titanium alloy rod whose hardness is second only to diamond, which greatly enhances the wear resistance of the high manganese steel hammer base. The materials are small and the impact force is small, so the double liquid bimetal high chromium composite hammer of Hebei Zhuxin can be used. The handle is carbon steel or low alloy steel, which has extremely high toughness and will not break. The wear part of the hammer is made of high chromium cast iron, with hardness up to HRC58-63, which has extremely high wear resistance. At the same time, special processes are used, and the two metals are well combined, Give full play to the different advantages of the two metals, which is the big advantage of bimetal composite hammers. When the size of the hammer is small and the weight is less than 15kg, the high chromium cast iron hammer of Hebei Zhuxin can be used. The extremely high hardness ensures excellent wear resistance.
