Products

High-carbon steel balls are spherical products made from carbon steels with a carbon content ranging from 0.60% to 1.70%. Their performance differs significantly from that of low-carbon steel balls, and their key characteristics are "high hardness and high wear resistance."

AISI 1085 high-carbon steel

Low-carbon steel balls are spherical products made from carbon steel with a carbon content ranging from 0.0218% to 0.25%. They exhibit good toughness, excellent weldability, easy machinability, and low cost.

AUSI 1010/1015 Low-Carbon Steel

Bearing steel balls are used in high-speed, low-noise bearings for bicycles, motorcycles, automobiles, slide rails, universal joints, luggage, and the electronics industry. They can also be used to grind other media.

Bearing steel balls

304 stainless steel balls are among the most widely used types of steel balls on the market. They can be applied in medical devices, chemical industry, aerospace, and plastic hardware—including perfume bottles, sprayers, valves, nail polish containers, motors, switches, electric irons, washing machines, refrigerators, air conditioners, pharmaceutical products, auto parts, bearings, instruments, and baby bottles.

304 stainless steel ball

316 Stainless Steel: Primarily used in fields such as medical devices, food machinery, cosmetic accessories, body jewelry, and instrumentation. The 316 stainless steel ball is a product with relatively high requirements and is typically employed in specialized industries including medical devices, chemical processing, aerospace, and aviation—such as perfume bottles, sprayers, valves, nail polish containers, body jewelry, and mobile phone circuit boards.

316/316L stainless steel ball

As a representative of martensitic stainless steels, 420 stainless steel balls combine high hardness, excellent wear resistance, and a certain degree of toughness. After heat treatment (quenching and tempering), they also exhibit outstanding corrosion resistance and polishability. They have good machinability and are ideally suited for manufacturing parts that endure high loads and high wear resistance.

420/420C Stainless Steel Ball

440C steel balls are spherical components made from high-carbon, high-chromium martensitic stainless steel. Their characteristics fully leverage the core performance of 440C steel and, combined with their “spherical shape,” make them ideal for applications such as bearings, grinding, and precision transmissions—resulting in three key advantages: hardness, wear resistance, and rust resistance.

440C stainless steel ball

Chrome steel balls are used in high-speed, low-noise bearings, as well as in bicycles, motorcycles, automobiles, slide rails, universal joints, luggage, and the electronics industry. They can also be used for grinding other media.
