1, composite hammer: composite hammer to carbon steel (e.g., steel No. 45) as the substrate, organic compound with high chromium cast iron (e.g. Cr20-28), made of cemented carbide block 4Cr22MoCu, hardness HRC52-58 . According to the shape and shape of the hammer, the position and number of the alloy blocks are determined, and the alloy blocks are combined into a desired shape.
2. Forging hammer: Forging hammer is to heat the metal to a temperature of 700-300 ° C, and then use a forging machine to apply pressure to the metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size. processing method. By forging osteoporosis can eliminate the disadvantages of metal such as cast produced in the smelting process, the optimization of the microstructure of the hammer, the mechanical properties are generally superior to the casting forging the same material.
3, high-manganese steel hammer: hammer high manganese steel high toughness, the process is also very good, inexpensive. When the hammer head is subjected to large impact or contact stress, the surface layer of the hammer head will rapidly produce work hardening, and the work hardening index is about 6 times higher than other materials, thereby greatly improving the wear resistance.
4, is a gold teeth hammerhead hammerhead high manganese steel reinforced ultra substrate, cemented titanium tungsten alloy is used as a host material that is wear on the wear-resistant high manganese steel alloy ingot mosaic hammer. The hammer head not only inherits the high toughness, high reliability and good wear resistance of the original high-quality enhanced ultra-high manganese steel, and has the wear resistance of super-hard tungsten-titanium alloy.
