Frequently Asked Questions
High chrome hammer heads offer significantly higher hardness (HRC 58-65) and superior wear resistance compared to high manganese steel, resulting in a service life that is often 3 to 5 times longer in abrasive environments.
They are ideal for the cement industry (ball mill liners), mining, metallurgy, and the chemical industry where crushing high-hardness materials is required.
We utilize multi-link testing, including Rockwell hardness tests, drop ball impact tests, and metallographic analysis to ensure the microstructure (M+A+C) meets strict industry standards.
Yes, we use a composite casting process and outside furnace refining, allowing us to customize the dimensions and alloy composition based on your specific technical drawings.
Generally, high chromium cast iron liners used in cement ball mills have a service life ranging from 6 to 12 years, providing extreme stability and reliability.
By employing the lost die composite casting process and precious metal elements, the Cr26 hammer achieves a hardness of 62-65 HRC, doubling the lifespan of standard hammers and reducing equipment maintenance costs.
