Frequently Asked Questions

What is the main difference between 304 and 316 stainless steel balls?

316 stainless steel balls contain molybdenum, providing significantly higher corrosion resistance than 304, making them ideal for medical and chemical applications.

Are these steel balls magnetic?

201, 304, and 316 are austenitic and generally non-magnetic (though 304 may become slightly magnetic after processing). 420 is martensitic and is magnetic.

What is the highest hardness available?

The 420 series martensitic stainless steel balls offer the highest hardness, reaching HRC 50-55.

Do you provide free samples?

Yes, free samples are available for quality testing and verification.

What are the available size ranges?

We provide a wide range of sizes from 2mm up to 25.4mm, with precision grades ranging from G10 to G1000.

What are your standard shipping terms?

We support Express (DHL/UPS/FedEx), Air Freight, and Sea Freight. FOB ports are typically Ningbo or Shanghai.
