High chromium iron steel ball

We can provide you with various brands of steel ball , also can customize and produce according to your working conditions

Balls in ball mills have different milling effects on materials depending on size, weight and material. Different sizes of steel balls can perform better milling in a certain proportion in the same abrasive silo.

Applicable materials: Cement, silicate, new building materials, refractory materials, ferrous and non-ferrous metals, glass ceramics, etc.

Our company provides professional matching service for steel ball, and at the same time, we recommend the steel ball material that is most suitable for your working conditions and materials.

High Chromiu iron

Chemical component

Grade	Chemical component %
Grade	C	Si	Mn	Cr	Mo	Ni	Cu	S	P
	≥10	≤1.2	≤2.0	14~18	≤3.0	≤2.5	≤1.2	≤0.06	≤0.10

Mechanical Property

Grade	Surface Hardness
	Casting condition		Hardened or hardened stress relief treatment Harded condition		Softening annealing condition
	HRC	HB	HRC	HB	HRC	HB
	≥46	≥450	≥58	≥650	≤41	400
1：There are no exact corresponing value between rockwell hardness(HRC) and brine hardness(HB),so ,this two kind of hardness value can be inspend used 2：The hardness in the 40%deepness of casting section should be lower than 92% hardness of surface.
