High-Chrome blow bars – 24%-27%Cr

High-chrome blow bars are widely used in horizontal rotor (HSI) and in some cases vertical rotor (VSI) impact crushers, available in 24%-27%Cr (High-Chrome ) or 18%-22%Cr (Medium-Chrome).

Due to the very high hardness, 600HB – 640HB, it offers a very high resistance in abrasive environments, if the working environment meets certain requirements: the small diameter of the feeding material (120-200 mm, depending on the size of the rotor) and the presence of a detector of metals / overband magnet to prevent contact with metals.

Having a low impact strength of 10 J/cm², white cast iron blow bars are prone to chipping/cracking and can create significant damage if the above recommendations are not followed.
