Superior Wear Resistance High-Chrome Cast Iron CR27 Hammer Head

he High-Chrome Hammer Head is engineered for extreme abrasion. With a chromium content of 20-30%, it achieves a hardness of HRC 58-65 on the working surface. This material is specifically designed for crushing highly abrasive materials like quartzite, basalt, and iron ore, delivering 3-5 times longer service life than traditional manganese steel.

Product Description

If your crusher eats through standard hammers in days, you need High-Chrome. This material is all about hardness. The high chromium content forms special carbides during casting—microscopic structures that act like armor plating against abrasive rock. Where it shines:

· Hard rock crushing: When processing materials with high silica content (like granite or river pebbles), the wear rate drops dramatically.

· Sharp edge retention: The working face stays sharp and effective throughout its life, maintaining crushing efficiency until the very end.

The trade-off: High-chrome is hard, which means it's slightly more brittle. It performs best in well-regulated crushers with consistent feed size and no metal contamination. For operations where "wear resistance" is the only priority, this is your best choice.
