Changzhou Eurasian is a leading high and low carbon steel ball manufacturing factory, offering both high carbon steel balls and low carbon steel balls designed for diverse industrial and mechanical applications. Our products combine hardness, durability, and precision, providing reliable performance for bearings, conveyors, roller skates, bicycles, and other rotating or load-bearing components.

Overview of Carbon Steel Balls

High and low carbon steel balls are made from carefully selected carbon steel grades and heat-treated to achieve the desired hardness and mechanical properties. Low carbon steel balls are typically case hardened, offering a hard exterior with a soft core, while high carbon steel balls are through-hardened, providing uniform hardness for heavy-load applications.

Features of Low Carbon Steel Balls

Low carbon steel balls are ideal for moderate-load applications where shock resistance and surface wear resistance are essential. Key characteristics include:

• Case hardened surface with soft core to resist impact and wear.

• High hardness (HRC 60 min) for durability.

• Available sizes: 2~38.1mm (2–1/2’’).

• Applications: Castors, conveyors, roller skates, drawer slides, seat slides, bicycles, and other rotating parts.

The combination of a hard exterior and soft interior allows for long-lasting performance in moderate-load industrial machinery.

Features of High Carbon Steel Balls

High carbon steel balls are through-hardened to provide consistent strength and longer life under high-load conditions. Features include:

• Through-hardened structure for uniform hardness.

• Hardness range: HRC 58–64.

• Sizes available: 2~38.1mm (2–1/2’’).

• Applications: Cycle industry, food industry, and other high-load environments requiring durability.

These balls are a cost-effective alternative to high carbon chrome alloy steel balls, providing excellent performance in demanding applications.

Material Standards and Conversions

Changzhou Eurasian produces carbon steel balls according to international standards, ensuring compatibility across applications:

• ASTM/AISI

• DIN

• W-Nr.

• NF

• JIS

Low carbon grades include CK15, S15C, while high carbon grades include CK85, S45C. High and low carbon steel ball manufacturing follows precise specifications to maintain consistent mechanical properties and dimensional accuracy.
