Descripción general del producto

AISI 1010/1015 Low Carbon Steel Balls are economical case-hardened carbon steel balls produced for semi-precision mechanical applications. Compared with soft unhardened carbon steel balls, these balls have a hardened outer layer created by carburizing and heat treatment. Compared with through-hardened chrome steel or high carbon steel balls, they offer a more cost-effective choice for moderate-load, low-to-medium speed applications where corrosion resistance is not the main requirement.

For buyers, the key value is practical durability: the surface provides wear resistance while the low-carbon core helps maintain toughness. This makes the product suitable for high-volume industrial hardware, furniture mechanisms, rolling systems, and general mechanical assemblies.

Material Selection & Technical Positioning

AISI 1010 and AISI 1015 are low carbon steels selected when manufacturers need a formable steel ball blank that can be case hardened to improve surface wear resistance. The material should not be described as stainless or corrosion-resistant. If the working environment is humid, outdoor, marine, acidic, alkaline, or food-contact, SDBALLS should recommend stainless steel balls, plated steel balls, or other material alternatives according to the application.

The correct industry terminology includes: low carbon steel balls, AISI 1010 steel balls, AISI 1015 steel balls, case-hardened carbon steel balls, carburized steel balls, and cemented carbon steel balls.

Heat Treatment, Hardness & Performance

AISI 1010/1015 low carbon steel balls are typically carburized and case hardened. This process creates a hard wear-resistant surface while keeping a lower-carbon core with better toughness than fully through-hardened high-carbon steel. For procurement and engineering approval, buyers should confirm not only the surface hardness but also whether case depth, core hardness or a specific hardness band is required.

Performance Item	Practical Guidance
Dureza superficial	Typically HRC 55-65 after case hardening
Case Depth	Depends on ball diameter and customer specification; confirm when wear life or load condition is critical
Core Characteristic	Lower-carbon core improves toughness compared with fully hardened high-carbon alternatives
Best Operating Fit	Moderate load, low-to-medium speed, cost-sensitive semi-precision mechanisms
Not Recommended For	High-speed fatigue-critical bearings, strong corrosion exposure, or applications requiring stainless performance

Technical FAQ

Q: What is the difference between AISI 1010 and AISI 1015 low carbon steel balls?

A: Both are low carbon steel grades. AISI 1015 generally has slightly higher carbon content than AISI 1010. For most semi-precision hardware applications, both can be specified as AISI 1010/1015 low carbon steel balls unless the buyer has a strict drawing or material requirement.

Q: Are these balls soft or hardened?

A: This page is for case-hardened / carburized low carbon steel balls. The surface is hardened, typically HRC 55-65, while the core remains tougher and lower in carbon. Soft unhardened balls should be listed and quoted separately.

Q: Are AISI 1010/1015 low carbon steel balls corrosion resistant?

A: No. Low carbon steel is not corrosion resistant. For rust-sensitive applications, buyers should consider oil protection, zinc/nickel/chrome plating, or stainless steel balls such as AISI 304, 316, 420C or 440C depending on the environment.

Q: What grades are available?

A: Common grades include G80, G100, G200, G500, G1000 and G2000. The most suitable grade depends on the application, required smoothness, load, motion type and target cost.

Q: What hardness can SDBALLS supply?

A: The standard case-hardened surface hardness is typically HRC 55-65. If case depth, core hardness or a narrower hardness range is critical, please confirm it before quotation and sample approval.

Q: Can these balls be plated?

A: Yes. Depending on the project, low carbon steel balls can be supplied plain, polished, oiled, zinc plated, nickel plated, chrome plated, copper plated or with other surface treatments. Plating thickness and final diameter tolerance should be confirmed before production.

Q: Can AISI 1010/1015 balls replace chrome steel balls?

A: Only in suitable applications. AISI 1010/1015 low carbon steel balls are economical for moderate-load, semi-precision use. For high-speed, high-fatigue or precision bearing applications, AISI 52100 chrome steel balls are usually more appropriate.

Q: What information is needed for a quotation?

A: Please provide material grade, diameter, precision grade, hardness, case depth if required, surface finish, quantity, packing, application, inspection document requirement, destination and trade term.
