Carbon Steel Balls

Low-carbon and high-carbon describe the material; soft or unhardened describes the delivery condition. BOYA’s material options include low-carbon AISI 1010/1015 and high-carbon AISI 1085. Soft low-carbon balls are commonly considered for welding and forming, while suitably hardened high-carbon balls are commonly considered for wear resistance. Select the material and treatment condition separately.

Not necessarily. Hardened 1010/1015 balls commonly use carburizing and case hardening, whereas 1085 high-carbon balls are commonly through-hardened. Surface and core hardness may differ, so one hardness value cannot describe all carbon steel balls. Confirm the heat-treatment condition, hardness test location and, where required, case depth.

They are processing methods, not additional material designations. Polishing improves the surface condition, hardening adjusts hardness, and plating produces a specified coating. BOYA’s listed options include polishing, heat treatment and copper, zinc or nickel plating. Assess combinations for the application and specify the coating requirements, final dimensions and acceptance criteria.

Chrome steel balls are commonly assessed first for precision bearings and demanding rolling-contact applications. Carbon steel balls in a suitable condition can be assessed for general mechanisms, slides and castors. Confirm load, speed, lubrication, environment, precision and hardness requirements. Do not substitute solely on price or material name.
