High Carbon Steel Ball

High Carbon Steel Ball

short cycle press machnie
High carbon steel balls are spherical components made of high carbon steel (carbon content is usually 0.6%~1.5%), usually produced by forging, heat treatment (throughout quenching and tempering), grinding and polishing. Compared with low carbon steel balls, high carbon steel balls have higher hardness and wear resistance, and are suitable for applications requiring high strength and durability.

How to Build High Carbon Steel Balls

line
Cold Heading

Cold Heading

short cycle press machnie

The cold heading uses equipmentZ32-7.5. The purpose is to be able to punch the steel wire out of the qualified ball blank. After the steel ball is cold heading, the next processing process is carried out.

Screening

short cycle hot press line

Screening, the balls after the hard grinding is initially screened through the screening machine, and the unqualified ball will be eliminated.

Screening
Polish steel balls

Polish Steel Balls

Polishing ball process is to initially polish the ball blank into a circle. It's a very important process.

Soft Grinding

The machine M360 is ued for soft grinding.

Soft Grinding
Heat treatment

Heat Treatment

short cycle press machnie

The heat treatment of the shaft steel ball is to raise the temperature in the furnace to 1050 ℃, the heat preservation time is 40-60 minutes, and the tempering time is 90 minutes. During the heat treatment process, the hardness, vulcanization, Metallographic structure and crushing load are clearly defined.

Oil Removal

Hard Grinding

Hard Grinding

Hard grinding is the method of grinding the ball after heat treatment with grinding wheel in the grinding machine. Its role is to further improve the accuracy and surface quality.

Measuring Instrumentation

After the hard grinding, the steel ball will be measured in accuracy, hardness, etc., and the three-needle measuring instrument will be used to check whether the expected effect is achieved.

Measuring Instrumentation
Cleaning

Cleaning

After screening, the steel ball is cleaned again and then dried.

Sorting

Features of High Carbon Steel Balls

line
High Carbon Steel Balls

  High-carbon steel balls achieve a hardness of HRC 60-66 after through-hardening, offering excellent wear resistance and suitability for high-load and abrasive environments.

  The high carbon content imparts excellent compressive strength and fatigue resistance, making them suitable for heavy machinery and rolling bearings.

  High mechanical strength ensures stability under cyclic loads and reduces deformation.

 The through-hardened structure ensures stability under high stresses, while also being economical, costing less than chrome steel or stainless steel balls.

Our Factory
Short-Cycle-Press-Machine

Changzhou Risheng Steel Ball Co., Ltd. is located on the eastern shore of Taihu Lake, adjacent to Shanghai, with convenient transportation. Since its establishment in June 1995, the company has been dedicated to developing and manufacturing steel balls, integrating research and development with trade.

For many years, Risheng building on the foundation of the Wujin Metal Ball Research Institute, has been committed to researching steel ball manufacturing technology. We primarily produce shaft steel balls (AISI 52100), stainless steel balls (AISI 201/304/316/420/440/430), and carbon steel balls (AISI 1015/1045/1085) with diameters ranging from 0.8mm to 25.4mm, with precision grades up to G10, G40, and G100. We also offer custom specifications for alloy steel balls, military steel balls, copper balls, UFO balls, ceramic balls, and other metal balls. 

Packaging & Deliver of High Carbon Steel Ball
Short-Cycle-Press-Machine

High-strength inner packaging: Shockproof foam bags or custom plastic boxes are used to secure each High Carbon steel ball in place, protecting it from impacts and scratches.

Moisture-proof protection: A moisture-proofing agent is added to effectively prevent the impact of moisture on the product during transportation.

Sturdy outer packaging: Thickened corrugated cardboard boxes or wooden pallets (for large orders) are used to ensure safe long-distance transportation.

Clear labeling: Product specifications, quantity, and drop warnings are clearly marked on the outer packaging box for easy verification and safe handling.

FAQ of High Carbon Steel Ball

  • Q Can High Carbon Steel Balls be Customized?

    A
    Yes, manufacturers offer custom sizes (0.5mm–50.8mm), tolerances, coatings (e.g., nickel for corrosion resistance), and heat treatments. They can be tailored for specific load capacities or magnetic properties.
    10. Where can I buy high carbon steel balls, and what should I consider?
    Suppliers like Hartford Technologies, Abbott Ball, Global Precision Ball & Roller, or BC Precision offer high carbon steel balls (e.g., AISI 1085). 

  • Q How are High Carbon Steel Balls Manufactured?

    A

    High carbon steel wire (e.g., AISI 1085) is cold-headed into blanks, flashed, and ground. The balls are then heated to ~1500–1600°F, quenched to lock in hardness, and tempered to reduce brittleness. Final grinding and polishing ensure dimensional accuracy and smooth surfaces. They meet ABMA standards for sphericity and tolerance (e.g., ±0.0001" for Grade 100).

  • Q What are the key properties of High Carbon Steel Balls?

    A
    • Hardness: Through-hardened to HRC 60–65, providing uniform hardness throughout.
    • Wear Resistance: High, suitable for heavy loads and wear-intensive applications.
    • Corrosion Resistance: Poor; prone to rust in humid or wet conditions without protection.
    • Magnetic: Fully magnetic, ideal for applications requiring magnetic properties.
    • Load Capacity: Excellent for higher loads compared to low-carbon steel, but more brittle.
    • Sizes and Grades: Available from 0.5mm to 50.8mm, in ABMA grades 100–1000 for varying precision.

  • Q What are high carbon steel balls, and what is their composition?

    A

    High carbon steel balls are made from steel alloys with 0.6–1.2% carbon, such as AISI 1060, 1070, or 1085. They contain iron as the primary element, with trace amounts of manganese, sulfur, and phosphorus, but minimal alloying elements like chromium (unlike chrome or stainless steel). They are typically through-hardened for uniform strength.
