Product Parameters

201 Stainless Steel Ball

Standard: American (SISI201), Japanese (SUS201), German (1.4372)

Application: Widely used in hardware industries, handicrafts, plastic products, lamps, motorcycle parts, luggage, and bearings.

Characteristics: Austenitic steel, non-magnetic, excellent performance with hardness HRC≤28. (Note: Not suitable for high anti-rust requirements like seawater).

304 Stainless Steel Ball

Application: Medical equipment, chemical, aviation, perfume bottles, sprayers, valves, motors, auto parts, and precision instruments.

Characteristics: Generally non-magnetic (may become slightly magnetic after processing), HRC ≤ 26. Excellent rust and corrosion resistance.

Comparison: 304L offers stronger anti-rust performance and superior polishing for high surface requirements.

316 Stainless Steel Ball

Application: Special industries like medical equipment, chemical, aerospace, body accessories, and mobile phone components.

Characteristics: Austenitic steel, HRC ≤ 26. Superior anti-corrosion performance compared to 304. 316L is softer and tougher, often used for jewelry/body accessories.

420 Stainless Steel Ball

Application: High precision industries: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, and petroleum valves.

Characteristics: Martensitic steel (stainless iron), magnetic, high hardness of HRC 50-55, good rust resistance.

Frequently Asked Questions

What materials of steel balls do you provide?

We offer a wide range of materials including stainless steel (201, 304, 316L, 420, 440C), carbon steel, bearing steel (GCR15), copper, glass, and titanium balls.

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

While both are austenitic and generally non-magnetic, 316 stainless steel balls contain molybdenum, providing superior corrosion resistance, especially against chlorides and industrial solvents.

Can the steel balls be customized?

Yes, we provide customization services for sizes ranging from 2mm to 25.4mm and different precision grades from G10 to G1000.

What is the typical hardness of the 420 series?

420 stainless steel balls are martensitic and heat-treated to achieve a high hardness range of HRC 50-55, making them ideal for bearings and valves.

Do you provide free samples?

Yes, we offer free samples for quality evaluation before placing a bulk order.

How long is the delivery time for bulk orders?

Standard delivery time is approximately 30 business days, depending on the order quantity and specification requirements.
