Product Description

Product Description

Stainless Steel Ball

Stainless steel balls are core components suitable for multiple scenarios, based on excellent corrosion resistance and multifunctionality. The materials cover 304/316L (austenitic), 440C (martensitic), etc., accurately matching different needs.

304 universal corrosion resistance, 316L has a threefold increase in chlorine resistance due to its molybdenum content, and no corrosion after 1000 hours of salt spray; The hardness of 440C reaches HRC58-62, and its wear resistance is comparable to that of bearing steel. The highest accuracy reaches G3 level, with a diameter tolerance of only ± 0.25 μm for G10 level, surface roughness Ra ≤ 0.025 μm, and operating vibration<30dB.

Widely used in medical (316L artificial joints), food (FDA certified equipment), marine (ship bearings), electronics (non-magnetic instruments) and other fields, stable operation in environments ranging from -270 ℃ to 400 ℃. Compared to ceramic balls, the cost is 70% lower, the lifespan of chemical equipment is 3-10 times longer than carbon steel balls, and maintenance costs are reduced by 60%.

By selecting the right material and precision as needed, stainless steel balls can provide durable and reliable performance support for products with corrosion resistance requirements.

Packaging & Shipping

Feige Steel ball packaging is based on "rust prevention as the core and sealing as the foundation", customized solutions for different materials and scenarios, comprehensively solving problems of rust prevention, moisture resistance, scratch resistance, and collision prevention.

Before packaging, the carbon steel balls are cleaned and cleaned with ultrasonic technology, dried with hot air (moisture content ≤ 0.05%), coated with anti rust oil, and precision steel balls undergo special anti rust treatment. The core protection adopts "gas-phase rust prevention+multiple sealing": carbon steel balls are wrapped in gas-phase rust prevention paper, and desiccants are added in high humidity environments; The precision steel ball is fixed with a groove partition box, which provides more precise anti scratch protection.

Buffer is adapted according to size, using 5mm pearl cotton for sizes below 50mm, large-sized steel balls with rubber buffer pads, and five layer corrugated boxes or thickened iron drums for outer packaging. The protection period for ordinary carbon steel balls is 6-12 months, while for G10 grade precision steel balls it is 18-24 months.

Each batch undergoes salt spray and drop testing, with clear warning labels on the packaging to ensure the quality of the steel balls remains as good as new after transportation and storage.
