Stainless Steel Balls are precision spherical components made from various grades of stainless steel. They're used in a wide range of applications requiring corrosion resistance, high strength, and dimensional accuracy.
🔧 Common Applications| Industry | Use |
|---|---|
| Bearings | Ball bearings, roller bearings, thrust bearings |
| Automotive | Fuel injectors, transmission systems, steering |
| Medical | Surgical tools, valves, pumps |
| Aerospace | Control systems, valves, actuators |
| Industrial | Valves, sprayers, flow meters, grinding media |
| Grade | Properties | Applications |
|---|---|---|
| AISI 304 | Good corrosion resistance, non-magnetic | Light-duty valves, food-grade uses |
| AISI 316 | Excellent corrosion resistance (marine/chemical), non-magnetic | Medical, marine, and chemical applications |
| AISI 420 | High hardness, moderate corrosion resistance, magnetic | Ball bearings, mechanical components |
| AISI 440C | Very hard and wear-resistant, magnetic, moderate corrosion resistance | High-precision bearings, aerospace |
| AISI 302/302B | Similar to 304, slightly higher tensile strength | Springs, instruments, less critical bearings |
Diameter: From under 1 mm to several inches
Precision Grades (per ABMA/ISO standards):
Grade 3–10: Ultra-precision (used in aerospace, high-speed bearings)
Grade 100–200: General industrial use
Finish: Mirror, matte, or rough (depending on use)
Hardness: Typically Rockwell C 55–65 (for 440C)
Corrosion resistance (especially in wet or chemical environments)
Strength and durability
Non-reactive (for food, pharma, medical uses)
Smooth surface finish (for low friction and precision)
