Outstanding Corrosion Resistance: Our AISI 304 steel balls deliver excellent passivity against food acids and atmospheric oxidation.
Food-Grade & Sanitary Safety : Our SUS304 stainless steel balls are thoroughly degreased and chemically stable, making them completely safe for food machinery and medical hardware.
Stable Non-Magnetic Performance : While cold heading introduces slight magnetism, Risheng utilizes a specialized hydrogen annealing process to thoroughly demagnetize our 1.4301 steel balls for sensitive cosmetic valves.
Superior Cost-Efficiency : Compared to 316L, our wholesale 304 steel balls offer a highly economical structural alternative for industries requiring solid rust prevention without high marine-chloride exposure.
Changzhou Risheng Steel Ball Co., Ltd. is located on the eastern shore of Taihu Lake, adjacent to Shanghai, with convenient transportation. Since its establishment in June 1995, the company has been dedicated to developing and manufacturing steel balls, integrating research and development with trade.
For many years, Risheng building on the foundation of the Wujin Metal Ball Research Institute, has been committed to researching steel ball manufacturing technology. We primarily produce shaft steel balls (AISI 52100), stainless steel balls (AISI 201/304/316/420/440/430), and carbon steel balls (AISI 1015/1045/1085) with diameters ranging from 0.8mm to 25.4mm, with precision grades up to G10, G40, and G100 for OEM precision steel balls . We are also Custom size steel balls manufacturer for alloy steel balls, military steel balls, copper balls, UFO balls, ceramic balls, and other metal balls.
1.High-Strength Inner Packaging & Surface Protection
To prevent metal-to-metal friction and surface abrasions, each 304L precision ball is secured using shock-absorbent materials.
Shockproof Foam Bags: Tailored for smaller batches to eliminate impact energy.
Custom Molded Plastic Trays: For high-precision grade orders, custom grids keep each stainless steel sphere isolated, preventing scratches and maintaining strict G10-G1000 tolerances.
2.Anti-Corrosion & Moisture-Proof Barriers
While 304-grade stainless steel offers excellent corrosion resistance, long-term sea freight exposure to salt air can be harsh.
Desiccant Integration: We include high-grade moisture-proofing agents (silica gel packs) within the primary seal.
3.Reinforced Outer Packaging for Global Transit
We offer scalable industrial-strength housing based on your order volume:
Heavy-Duty Corrugated Cartons: Double-walled, thickened fiberboard tested for burst strength.
4.Precision Labeling & Traceability
Every shipment features comprehensive logistical labeling to streamline your warehouse receiving process:
Product Specifications: Clear marking of Grade (304/304L), Diameter (mm/inch), and Quantity.
Quality Assurance: Batch numbers for full material traceability.
