The materials for high-manganese steel hammer heads include tungsten-molybdenum alloy bars with Mn13Cr2, Mn18Cr2, Mn13, or Mn18 inserts and wear-resistant surface coating alloys.
When the high-manganese material withstands high impact force from the stone, its surface hardens rapidly and forms a wear-resistant surface layer. The hard alloy bar with insert showed good anti-friction, hardness, and wear resistance performance. Toughness
Features:Good toughness, good manufacturability, low price, but the overall performance requirements of the crusher are higher.
Applicable working conditions: Suitable for cement plants, metal recycling, stone factories and other rocky locations with poor conditions.

The working part of the hammer head is made of high-chromium cast iron, with high wear resistance, and the handle is made of high-tenacity alloy steel.
Features:High wear resistance
Applicable working conditions:Limestone, cement clinker, iron ore, sandstone, coal gangue, basalt and other hard stone crushing areas.
Operating principle:The motor drives the rotor to rotate at high speed in the crushing chamber. The hammer is the main wear part, and the quality of the hammer directly affects the crushing efficiency of the crusher. During operation, the hammer is not only hit but also impacted by the material. If used repeatedly for a long period, the working surface of the hammer will be damaged and the shape of the surface will change.
We use appropriate alloys and related technological measures to ensure that the surface hardness of the high-chromium iron hammers reaches more than 58 HRC and, during the wear process, maintains high hardness and high wear resistance.
Applicable working conditions:Suitable for the manufacture of wearable replacement parts with lower impact load and simpler shape.
