We use proper alloying and and related technological measures to make High chromium iron blow bars’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.

1：There are no exact corresponing value between rockwell hardness(HRC) and brine hardness(HB),so ,this two kind of hardness value can be inspend used 。 2：The hardness in the 40%deepness of casting section should be lower than 92% hardness of surface.

In the process of using ceramic blow bars, because ceramic high chromium cast iron have excellent wear resistance that other wear-resistant materials can not match, it greatly reduces the consumption of user materials and the labor cost of replacing wear-resistant parts, and becomes the representative of a new generation of wear-resistant materials.
