1. Key Properties
AISI/SAE 1030 is a medium-carbon steel that provides a good balance of strength, ductility, and machinability. This steel is commonly used for parts that require moderate strength and hardness. It offers good weldability and is easy to form, making it versatile for various applications. While it has moderate tensile strength, it is suitable for applications where high toughness, wear resistance, and the ability to absorb shock are important.
2. Applications/Industries
Automotive: Parts such as axles, gears, and shafts that require moderate strength and toughness.
Heavy Machinery: Components like crankshafts, spindles, and other structural parts exposed to moderate mechanical stress.
Tool Manufacturing: Dies and tools that are subject to moderate wear.
Construction: Structural components, beams, and supports requiring basic strength and durability.
Industrial Equipment: Parts in power transmission systems such as shafts, couplings, and cams.
3. Certifications/Standards
ISO 9001 Certified: Ensures high manufacturing quality and consistency.
Meets AISI/SAE 1030 Specifications: Complies with the American Iron and Steel Institute (AISI) and Society of Automotive Engineers (SAE) standards for medium-carbon steels.
