Product Overview

AISI 1085 High Carbon Steel Ball is a through hardened carbon steel ball engineered for high hardness, superior wear resistance, and dependable performance in repeated-contact mechanisms. Based on decades of manufacturing expertise and proven export supply programs, this grade is widely specified when customers need a cost-effective, wear-focused steel ball that maintains stable mechanical behavior across high-volume production.

Through hardened AISI 1085 balls are forged from steel where high carbon content is the primary alloying element and other elements include silicon, manganese, copper, aluminum, chromium, molybdenum, and nickel. This composition and processing route supports very good hardness and wear resistance for semi-precision bearing systems, sliding mechanisms, and general industrial hardware requiring consistent rolling and load transfer.

Produced by Shandong SDBALLS Industry Co., LTD, a professional steel ball manufacturer in China with more than 30 years of production experience, these balls are supplied with strict process control, flexible OEM and ODM customization, and ontime delivery planning. SDBALLS operates two factories with modern production equipment, produces more than 5,000 tons annually, and exports 100 percent of products to customers in more than 50 countries.
