Stainless steel balls are usually produced by stainless steel forging process. Currently, commonly used materials for stainless steel balls include 201, 302, 304, 316, 316L, 420, and 440C. Stainless steel is a steel alloy that contains more than 11% chromium. This type of steel has high resistance to corrosion by chemicals (acids, alkalis, salts). Therefore, it solves traditional steel's corrosion problem and provides excellent resistance to rust and coloring.

AISI 304 Stainless Steel Ball
Diameter : 0.5mm to 50.8mm
Surface: High polish
Hardness: HRC10-20
Grade:G100-G1000
Speciality: A representative of Austenitic stainless steel.it is nonmagnetic,but magnetic after rolling, and the magnetism can be taken out, HRC≤25.It has good anti-rust and anti-corrosive capability.
Comparison: 304HC stainless steel ball is softer and can be processed more easily than 304 stainless steel ball, while 304L stainless steel ball has stronger anti-rust and anti-corrosive capability than the above two, It can be jointed easily.

AISI 316 Stainless Steel
Diameter: 0.5mm to 50.8mm
Surface: High polish, electroplat
Hardness: HRC20
Grade: G100-G1000
Magnetic: Austenitic steel, non-magnetic
Features: the most suitable for industries with high anti-corrosion requirements, and the anti-rust ability is very strong.
Applications: Valves, perfume bottles, medical equipment, nail polish, baby bottles, cosmetic packaging, air conditioners

AISI 420C stainless Steel
Size: 0.3mm- 50.8mm
Grade: G10-G1000
Hardness: HRC50-55
Magnetic: Martensitic steel, magnetic
Features: Commonly known as stainlessiron, good corrosion resistance and toughness..
Applications: All kinds of precision machinery, bearings, electrical equipment,household appliances, auto parts, etc.

AISI 440C Stainless Steel
Size: 0.3mm- 50.8mm
Grade : G10-G1000
Hardness: HRC55-60
Magnetic:Martensitic steel, magnetic
Features: high precision, good corrosion resistance, strong rust and wear resistance.
Applications: Bearings, stamping / hydraulic parts, valves, aerospace, seals, refrigeration equipment, high-precision instruments, etc.
