Detailed Description
Forged Steel Ball Features and Advantages:
Concentrating on wear-resistant grinding material for 30 years, Huamin Brand steel grinding ball is excellent in surface quality, hardness, and resistant to impact and abrasion. It won't crack and lose circularity easily.
1) High Hardness: Huamin forged grinding steel ball has high hardness: surface hardness can reach to 55-67 HRC, volume hardness 56-64 HRC
2) High Impact Toughness: impact toughness is more than 12 J / cm2.
3) Low Broken Rate: peel fragmentation resistance property of over 20000 times. The actual breakage rate is less than 1% and close to 0.
 
Cast Ball's Product Quality Standard and Inspection Method
Our cast iron grinding balls can be divided into three categories including the high chromium type, medium chromium type and the low chromium type.
The Quality Index of the High Chromium Type
The chromium content of the high chromium type product is greater than or equal to 10.0%. And the carbon content is between 1.8% and 3.20%. It is required by the national standard that the hardness of the high chromium type product must be no less than 58HRC, and that the impact value should be greater than or equal to 3.0 J/cm2. This type of product must go through the hot quenching and the tempering treatment to come up to the hardness.
 
Currently in China, there are two quenching methods for this type of product including oil quenching and wind quenching. If the tested hardness of this type of product is below 54HRC, then it shows that the quenching treatment is omitted.
Product Quality Standard and Inspection Method
The chemical composition of the high chromium type product should conform to the below table. We can also manufacture the product with special chemical composition in accordance with the requirements of the customers.
