FAQ
What information do you need for a quotation?
Please share the ball size, material grade, quantity, grade requirement if any, application, and delivery term such as FOB or CIF.
What is the difference between 304 and 304L stainless steel balls?
304L stainless steel balls have lower carbon content than 304, which improves resistance to intergranular corrosion, especially in welded or heat-affected environments.
Are 304 stainless steel balls corrosion resistant?
Yes, 304 stainless steel balls offer good corrosion resistance in water, humidity and mild chemical environments. For stronger corrosion resistance, 316 / 316L stainless steel balls may be more suitable.
Are 304 stainless steel balls magnetic?
304 stainless steel balls are generally non-magnetic in annealed condition, but slight magnetism may appear after cold working. Demagnetization can be arranged if required.
Are 304 / 304L stainless steel balls suitable for food equipment?
Yes, 304 / 304L stainless steel balls are commonly used in food processing equipment, dispensers, pumps and valves where corrosion resistance and clean surface finish are required.
Can you provide custom sizes or special requirements?
Yes, we can support custom sizes, grade requirements, surface conditions and packaging. MOQ may vary depending on size and specification.
Can you provide samples for testing?
Yes, samples are available for testing and evaluation. Standard sizes are usually easier to arrange from stock.
Do you provide inspection reports or material certificates?
Yes, inspection reports can cover dimensions, tolerance and surface condition. Material certificates are available upon request.
What packaging options do you offer?
We can provide cartons, steel drums, bulk bags or customized packing according to customer requirements.
Can 304 stainless steel balls be used for high-load bearing applications?
304 stainless steel balls are mainly selected for corrosion resistance rather than high hardness. For high-load bearing applications, chrome steel or 440C stainless steel balls may be more suitable.
