Changzhou Huari Steel Ball Co., Ltd is an ISO9001: 2015 and IATF16949: 2016 certified professional manufacturer of steel balls, with experience of more than 40 years.
The factory produces ball sizes from 0.5mm to 250mm. The main products is as follows.
1. Stainless steel balls:
The production of stainless steel balls can be divided into two types.
a． AISI304, 304L, 316, 316L balls (G100-G1000).
All these kinds of balls will have a slight magnet after heading. Some customers do not need such magnet. So, we need to demagnetize them by high temperature, using nitrogen as the protection atmosphere in the furnace, so balls can still have a good anti-rust ability after this process.
Such kind of balls are widely applicated in beauty industry and where strong anti-rust ability is needed.
b． AISI420, 420C, 440, 440C(G10-G1000) .
Such balls can be hardened by heat treatment. Normally, such balls are used as rolling elements and are applied in an environment that needs both hardness and anti-rust ability for the parts.
2. AISI52100/SUJ-2/100Cr6/100C6/1.3505 Chrome steel balls:
The whole manufacturing process of annealing of raw material, heading/cutting, flashing, heat-treatment, grinding, lapping, and inspection are all done in our own factory, which guarantees our chrome steel balls with perfect diameter tolerance, roundness, surface, and stable hardness.
Our chrome steel balls are widely used in cars industry, bicycles, bearings industry, and working as grinding media.
3. Carbon steel balls:
The main material we are producing are AISI1010-1015, AISI1045, AISI1085, AISI1086, etc.
Such carbon steel balls are widely used in castors, bearings, wheels, drawer slides, or working as grinding media.
