Manufacturing process

Renowned for their superior durability, our high chromium balls boast a minimum chromium content of 10.0%. These balls adhere strictly to the national standards, ensuring a hardness (HRC) exceeding 58. Their robust impact value, AK ≥3.0J/ 2, is achieved through meticulous high-temperature quenching and tempering treatments, guaranteeing exceptional performance.
Low chromium balls, with chromium content ranging from 1-3%, also deliver reliable performance and are crafted to meet rigorous industry specifications.
