High Chrome Cast Grinding Stell ball
High Chrome Cast Grinding Stell ball
Chromium content ≥10.0%, carbon content between 1.80%-3.20% 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, if the hardness of high chromium ball must use high temperature quenching + tempering treatment (at present domestic high chromium ball quenching oil quenching and wind quenching two quenching methods), If the test hardness (HRC) is below 54, the High chromium cast steel ball has not been quenched.
High Chrome Cast Grinding Stell ball
We produce High Chrome Cast Grinding Stell ball for over 20 years and supply distinct mining groups like gold mine, copper mine, zinc mine, iron mine from ghana, mexico, canada, south africa, chile, peru, congo, zambia and so forth; advanced control ideas, state-of-the-art technique system, and terrific group of workers have applied the suitable quality attraction in each hyperlink of the manufacturing system, and found out the complete upgrading of product quality
