Blow Bar and Hammer Material Selection

① Manganese Steel (Mn14% / Mn18% / MNX50): High impact resistance, suitable for primary crushing containing impurities. MNX50 is our optimized high-performance grade, proven to have a longer service life than standard manganese steel hammers.

② Chromium Iron (Cr20% / Cr26%): High hardness and wear resistance, suitable for general working conditions without impurities. However, note that it is brittle; impurities can cause serious damage.

③ Martensitic Alloy Steel: Combines the impact resistance of manganese steel with the hardness and wear resistance of chromium iron. Commonly used in quarrying and recycling industries, it outperforms manganese steel in abrasive conditions.

④ Chromium Iron + Ceramic Matrix: High-quality composite material with a wear-resistant surface inlaid with hard ceramic alloy, significantly longer service life than standard chromium iron bars. Suitable for secondary crushing, but not suitable for primary crushing or extremely hard materials.

⑤ Martensitic Alloy Steel + Ceramic Matrix: Ceramic inserts + martensitic steel matrix, longer service life than standard martensitic steel bars. Suitable for primary crushing in the recycling industry and quarries, but not suitable for limestone and slag recycling.

All HAUSMIING® compatible crusher parts are manufactured and warranted by HAUSMIING®, for the avoidance of doubt it is not implied that our branded parts originate from the OEM.
