The materials of high manganese steel blow bars include Mn13Cr2, Mn18Cr2, Mn13 or Mn18 ｉｎｓｅｒｔ tungsten-molybdenum alloy bars and surfacing wear-resistant alloys.
Our company's newly developed ceramic composite matrix reinforced blow bar incorporates cermet into a traditional high-manganese steel matrix, forming a multi-level composite material through in-situ self-generation technology. This blow bar exhibits twice the hardness of Mn18Cr2 at room temperature, and its hardness decreases only slightly at high temperatures compared to room temperature, thus solving the problem of significant attenuation of wear resistance in high-manganese steel with increasing temperature.
Applicable working conditions: Suitable for cement plant, stone factories and other rocky places with poor conditions.

Standard wear-resistant material with excellent impact resistance and work hardening properties.
Enhanced wear resistance with embedded alloy bars for superior performance in high-abrasion conditions.
Advanced ceramic composite matrix reinforcement technology for extended service life.
Bimetal composite structure combining wear-resistant surface with tough core material.
Excellent wear resistance with good hardness retention at elevated temperatures.
Rebuilding and reinforcement using advanced hardfacing welding technology.
Customized according to your operating conditions
For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.
For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.
For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
We will fully understand your working conditions and recommend the most appropriate material selection. Provide drawings based on your machine models and spare parts dimensions.
