Wear Resistant High Chrome Cast Iron Crusher Hammer
a. Sand casting, lost foam casting, investment casting.
b. 2 times more wear-resistent than high manganese steel hammer.
c. With compound casting process: hammer head high chrome cast iron, handle cast steel.
d. ISO9001:2008.
e. All necessary inspections available.
Material of crusher hammer is normally high manganese steel such as Mn13, Mn18, Mn22, Mn13Cr2, Mn18Cr2, Mn22Cr2, Mn13CrMo, Mn13CrMoNi.
Our crusher hammer is made of high chrome cast iron, KmTBCr12, KmTBCr15Mo, KmTBCr20Mo, KmTBCr26, etc. High chrome cast iron hammer is more wear-resistant than high manganese steel hammer.
Compand casting process is applied: hammer head is made of high chrome cast iron, handle is cast steel, which ensures the hammer both wear-resistant and impact-resistent.
