Martensitic Steel/Ceramic

This blow bar consisting of hard ceramic particles on the wear surface in a martensitic steel matrix. This composite has the effect of combining the very hard surface of the ceramic with the useful mechanical properties of steel. These blow bars can have two to four times the life of standard mono-alloy blow bars. Its steel hardness rang 44-57HRC, the impact strength is 100-300 J/cm3.
