Crusher Blow Bars Material
Manganese Steel Blow Bars
Manganese steel blow bars are commonly used primary crusher applications and provide high shock resistance and are available in both Mn14% and Mn18% material grades. They are well suited to applications where tramp iron is possible in the feed material. Manganese bars are often used as a ‘safe’ choice, however, other materials available can offer significant life costs benefits.The wear resistance of manganese steel with austenitic structure is attributable to the phenomenon of working hardening. The impact and pressure load results in a hardening of austenitic structure on the surface.
Martensitic Steel Blow Bars
Martensitic steel blow bar is one of the kinds of impact crusher blow bars. Martensitic Steel will be used whenever hardness and impact resistance are both needed, e.g. in primary and recycling applications. The martensite is a completely carbon-saturated type of iron by special heat treatment for improving the strength and wear properties, which lie between manganese steel and chrome steel. The steel hardness ranges from 53 to 58HRC and the impact strength is about 50J/cm2.
Chromium Steel Blow Bar
High chromium steel is widely to use in casting impact crusher wear parts. The impact crusher wear parts include crusher blow bar and impact plate. As normal, Cr21 and Cr26 are used in casting crusher blow bars; the Cr15 material used in casting impact plate.
Ceramic Matrix Composites Blow Bar
Ceramic Matrix Composites Blow Bar is one of the normally impact crusher wear parts. Ceramic Matrix Composites Blow Bar include martensitic ceramic matrix composites blow bars and high chromium matrix composites blow bars.
Titanium Carbide Insert Blow Bars
Titanium carbide insert blow bars mean manganese steel or alloy steel as a matrix body, insert titanium carbide bars into the body. Under this design, the tic inserts blow bars span life more than other material. Titanium carbide insert blow bars is supplied by Qiming Machinery.
