AISI 1030 Steel Product Information -:- For detailed product information, please contact sales. -: # **Technical Datasheet: AISI 1030 Steel** ## **1. Overview** AISI 1030 is a standard medium-carbon steel grade renowned for its excellent balance of strength, ductility, and wear resistance. As part of the American Iron and Steel Institute (AISI) 10xx series of plain carbon steels, it offers reliable performance in both normalized/annealed and heat-treated conditions. The carbon content (approximately 0.30%) provides good hardenability for surface treatments while maintaining sufficient toughness for dynamic loading applications. This versatile engineering steel is widely available in various forms including bar, plate, sheet, and forging stock, making it a fundamental material choice across multiple industries. ## **2.
