Stainless Steel Balls

Stainless Steel (AISI 304)

Stainless steel balls come in various types, including AISI 304, AISI 316, AISI 316L, AISI 420, AISI 420C, AISI 440, and AISI 440C. AISI 304 steel balls have low hardness but excellent corrosion resistance, making them suitable for applications involving corrosion, dyes, food processing, valves, and adult products.

Our factory's AISI 304 stainless steel balls:

Minimum Diameter: 2mm

Accuracy: G100

Hardness: HRc25-39

Stainless Steel (AISI 316L)

AISI 316L stainless steel ball has a lower carbon content than AISI 316, offering enhanced corrosion resistance and excellent resistance to sulfur compounds.

Commonly used for valves and jewelry applications.

Our factory's AISI 316L steel ball:

Minimum Diameter: 2mm

Accuracy: G100

Hardness: HRc25-39

Stainless Steel (AISI 420)

AISI 420 features good hardness, excellent corrosion resistance, and strength, commonly used in all applications requiring corrosion resistance.

Bearings, valves, writing instruments, food environments, freshwater, many petroleum products, and corrosive materials in weakly acidic environments. AISI 420 is also magnetic.

Our factory's AISI 420 stainless steel balls:

Minimum Diameter: 1.2mm

Accuracy: G10

Hardness: HRc52

Stainless Steel (AISI 420C)

AISI type stainless steel balls offer the advantages of maximum hardness and corrosion resistance.

Characteristics: The hardness range of the 420C ball is slightly higher than that of the 420. Its excellent surface finish also makes it particularly suitable for bearings, valves, and other harsh environment applications.

Our factory's AISI 420C stainless steel balls:

Minimum Diameter: 1.2mm

Accuracy: G10

Hardness: HRc52

Stainless Steel (AISI 440)

AISI 440 stainless steel ball bearings are widely used for their hardness, dimensional stability, corrosion resistance, and toughness. The 440 balls can withstand corrosion from fresh water, steam, gasoline, sweat, alcohol, blood, and food. Maximum corrosion resistance and rust prevention can be achieved only when the 440 balls are fully hardened, allowing for high-gloss surface polishing. The 440 balls are also magnetic.

Our factory's AISI 440 stainless steel balls:

Minimum Diameter: 1.2mm

Accuracy: G10

Hardness: HRc60-67

Stainless Steel (AISI 440C)

AISI 440C steel balls offer the highest strength and excellent corrosion resistance in stainless steel materials. They also possess good hardness, making 440C steel balls commonly used in bearings, valves, and more.

Our factory's AISI 440C stainless steel balls:

Minimum Diameter: 1.2mm

Accuracy: G10

Hardness: HRc60-67
