Product Overview

Soft Unhardened Carbon Steel Ball is a low-carbon steel ball engineered for cost-effective forming, welding capability, and general-purpose industrial use where high hardness is not required. Produced from AISI 1010-1015 low-carbon steel, these balls provide reliable dimensional consistency across metric and imperial sizes and are commonly selected for decorative hardware, toys, wrought iron work, and mechanical movement components such as curtain mechanisms. They are also widely used in hunting shot, slingshot, munitions, stirrers, and mixers where magnetism and basic mechanical strength are acceptable.

Engineered and tested across thousands of installations based on decades of manufacturing expertise, soft unhardened carbon steel balls are chosen for applications that value machinability, weldability, and economical supply. With hardness HRB 60 to 90 and precision grades G200, G500, and G1000, this product supports a wide range of functional assemblies and bulk consumption use cases.

Technology & Design Highlights

Soft Unhardened Carbon Steel Ball performance is achieved through controlled low-carbon material selection, cold forming, and disciplined inspection for semi-precision grades.

Low-Carbon Steel For Forming And Fabrication

AISI 1010 and AISI 1015 compositions provide a low-carbon foundation that supports welding capabilities and general fabrication use. The listed chemical composition ranges for carbon, silicon, manganese, phosphorus, and sulfur support predictable material behavior across bulk production and downstream processes.

Semi-Precision Grades For Cost-Performance Balance

Precision grades G200, G500, and G1000 are suited to applications where controlled spherical geometry is required without the cost and processing of high-precision bearing balls. This allows economical adoption across decorative, mechanical, and bulk usage segments.
