Product Description
We are the leading manufacturer of High Chromium and Low Chrome Casting Steel Ball. Established in 1995, to serve the cement, mineral processing, power plant, chemical and other industries more than 20 years.
Chromium content ≥10.0% are called high chromium ball, the national standard requirements of high chromium ball hardness (HRC) must be more than 58, impact value AK ≥3.0J/ 2, must use high temperature quenching + tempering treatment.
Chromium content 1-3%% are called low chromium ball.
