AISI 304/ 302/303
Characteristics: Austenitic, corrosion resistant, slightly magnetic; however, annealing can render it non-magnetic.
General applications: Used in valves and related applications, food, aerosols, household sprays, perfumes and medical devices.


Automation Equipment and Transfer Mechanisms
In factory workshops, assembly lines, and light automation environments, equipment builders often need ball components that maintain stable movement and resist moisture or routine cleaning exposure. In this scenario, the G500 304 stainless steel ball serves as a reliable rolling, positioning, or contact element in feeders, guides, and transfer mechanisms, helping support consistent mechanical action with less concern about surface corrosion. Its available diameter range makes it practical for both compact modules using small steel balls and larger assemblies that need matching component sizes within the same project.
Valve, Hardware, and Custom Component Production
In hardware manufacturing plants, fluid control workshops, and custom machining environments, users may need stainless spherical parts that are easy to integrate into valves, dispensers, check mechanisms, or modified metal assemblies. The G500 304 stainless steel ball fits this scenario because it provides a stable base component for direct use or secondary processing, including projects related to a steel ball with hole or threaded steel ball configurations. For manufacturers balancing corrosion resistance, sourcing efficiency, and compatibility with standard production methods, it is a practical option from the perspective of long-term industrial use and repeatable fabrication.

Q1. What material is this ball made from, and is it suitable for general industrial use?
The ball is made from 304 stainless steel in G500 grade, with sizes from 0.3mm to 25.4mm. We supply it for general-purpose industrial applications where corrosion resistance and dimensional consistency are important, and our team can help confirm fit for your process.
Q2. Do you offer multiple size options for different equipment and assembly needs?
Yes, we provide this stainless steel ball across a wide size range, from 0.3mm up to 25.4mm. Our selection supports varied assembly, motion, and component requirements, including applications that use small steel balls for compact mechanical designs.
Q3. Can I use this product as a substitute for bearing components in my system?
The specified product is a 304 stainless steel ball, not a separately defined bearing steel balls grade in the provided data. We recommend reviewing your load, hardness, and corrosion requirements with us before selecting it for bearing-related assemblies.
Q4. Do you provide special formats such as a steel ball with hole or a threaded steel ball?
No special machining details are listed for this item. Our current product information covers a G500 304 stainless steel ball in standard size options only, so we advise confirming any hole, thread, or other modification requirements with us before ordering.
Q5. How should I evaluate this product when comparing steel ball manufacturers for procurement?
A practical comparison should focus on stated material, grade, and size range. This item is defined as a G500 304 stainless steel ball from 0.3mm to 25.4mm, and we recommend using those core specifications to match your drawing, tolerance, and application requirements.
