304/304L Stainless Ball Manufacture

How to Build 304/304L Stainless Steel Balls

Cold Heading

The cold heading uses equipmentZ32-7.5. The purpose is to be able to punch the steel wire out of the qualified ball blank. After the AISI 304 Stainless steel balls is cold heading, the next processing process is carried out.

Screening

Screening, the balls after the hard grinding is initially screened through the screening machine, and the unqualified ball will be eliminated.

Polish Steel Balls

Polishing ball process is to initially polish the ball blank into a circle. It's a very important process.

Soft Grinding

The machine M360 is ued for soft grinding.

Oil Removal

Oil removal equipment, put the ball into the equipment, after screening, separate the ball from the oil.

Hard Grinding

Hard grinding is the method of grinding the ball after heat treatment with grinding wheel in the grinding machine. Its role is to further improve the accuracy and surface quality.

Measuring Instrumentation

After the hard grinding, the steel ball will be measured in accuracy, hardness, etc., and the three-needle measuring instrument will be used to check whether the expected effect is achieved.

Cleaning

After screening, the steel ball is cleaned again and then dried.

Sorting

After cleaning, the steel ball will be qualified into the container through the sorting machine, and finally manually test to complete the whole process of steel ball production.

Our Factory

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. 

Packaging & Delivery of 304/304L Stainless Steel Ball

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.
