The materials of high manganese steel hammer heads include Mn13Cr2, Mn18Cr2, Mn13 or Mn18 ｉｎｓｅｒｔ titanium alloy bars and hardfacing.
When the high manganese material bear large impact force from Stone, its surface hardening quickly and forms the wear resistance surface layer. The ｉｎｓｅｒｔ hard alloy bars had good performance anti-friction ,hardness & toughness.
Features:Good toughness, good manufacturability, low price, but the overall performance of the crusher requirements are higher.
Applicable working conditions: Suitable for cement plant, metal recycling, stone factories and other rocky places with poor conditions.

The working part of the crusher hammer head is made of high-wear-resistant high-chromium cast iron, and the handle is made of high-toughness alloy steel.
Features: High wear resistance
Applicable working conditions: Limestone, cement clinker, iron ore, sandstone, coal gangue, basalt and other hard stone crushing fields.
We use proper alloying and and related technological measures to make High chromium iron hammers’ surface hardness reaches more than 58HRC , during the process of wearing will maintain high hardness and high wear resistance.
Applicable working conditions: Suitable for making wearable spare parts with lower impact load and simpler shape.
