Stainless Steel Balls
Stainless steel balls, particularly AISI304 and AISI316, are known for their excellent corrosion resistance. They are commonly used in medical applications, food processing, and aerosol dispensers. AISI316 offers superior resistance to sulfuric acid, making it ideal for harsh environments.
Carbon Steel Balls
Carbon steel balls are less expensive and are typically used in applications where corrosion resistance is not a primary concern. They are commonly found in anti-friction bearings, casters, and various machinery components.
Chrome Steel Balls
Chrome steel balls, made from AISI52100, are known for their high hardness and wear resistance. They are widely used in tools, drills, and bearings, providing excellent performance in demanding applications.
AISI420C and AISI440C Balls
AISI420C and AISI440C stainless steel balls offer a balance between corrosion resistance and hardness. They are suitable for applications in valves, lighters, and locking mechanisms, where both strength and resistance to corrosion are required.
Manufacturing Process of Steel Balls
The manufacturing process of steel balls involves several key steps:
- Cold Heading: Rough ball shapes are forged from bar stock material.
- Deflashing: Rough machining or soft grinding removes the forge flashing.
- Heat Treatment: Balls are heat treated based on technical specifications in a controlled process.
- Finishing: Stainless steel balls skip this step, while other steel balls may be hardened using heat treatments.
- Hard Grinding: The steel balls are ground to remove nicks and imperfections.
- Lapping: A controlled mechanical sanding/polishing process ensures spherical accuracy.
- Inspection & Packaging: Lubricant or rust-preventive is applied before inspection and packaging.
Applications of 5mm Steel Balls
5mm steel balls are versatile and find applications across various industries:
– Automotive: Used in bearings and other moving parts.
– Medical: Essential in devices like aerosol dispensers and medical equipment.
– Manufacturing: Employed in machinery, tools, and production lines.
– Consumer Products: Found in toys, sports equipment, and household items.
