1. Key Properties
AISI/SAE 1040 Hot Drawn Flat Bars are medium-carbon steel bars that provide a good balance of strength, ductility, and machinability. The hot drawing process ensures excellent dimensional accuracy and a smooth surface finish. 1040 steel has moderate tensile strength, hardness, and wear resistance, making it ideal for applications where moderate stress and impact resistance are required. It is also relatively easy to machine, weld, and form, providing versatility in fabrication.
2. Applications/Industries
Automotive: Parts such as axles, gears, shafts, and camshafts that require moderate strength and toughness.
Heavy Machinery: Components like spindles, shafts, and structural elements exposed to moderate mechanical loads.
Tool Manufacturing: Dies, molds, and tools requiring medium hardness and toughness.
Construction: Structural beams, supports, and components used in building projects.
Industrial Equipment: Shafts, rods, and couplings in machinery and power transmission systems.
3. Certifications/Standards
ISO 9001 Certified: Ensures high-quality manufacturing standards and consistent production.
Meets AISI/SAE 1040 Specifications: Complies with the American Iron and Steel Institute (AISI) and Society of Automotive Engineers (SAE) specifications for medium-carbon steels.
