Applications of 1035 Carbon Steel
SAE/AISI 1035 carbon steel is widely used in numerous industries due to its moderate strength, good machinability, and formability. It is ideal for a range of applications, including:
- Shafts and Axles: Used in machinery, automotive components, and agricultural equipment, where moderate strength and wear resistance are required for transmitting torque and handling rotational loads.
- Bolts, Nuts, and Fasteners: Commonly used for manufacturing bolts, nuts, and fasteners due to its good machinability, which allows for easy production of threaded components for secure connections.
- Gears and Sprockets: Suitable for gears and sprockets in applications where high strength is not essential, such as gearboxes, mechanical power transmission systems, and industrial machinery.
- Couplings and Fittings: Employed in the production of couplings, fittings, and connectors used in piping systems, hydraulic systems, and fluid handling applications, thanks to its formability and weldability.
- Construction Components: Utilized in construction components like beams, columns, and structural parts for projects where moderate strength is sufficient, such as in building frameworks and bridges.
- Tools and Dies: When heat-treated, it is used in producing tools and dies, including cutting tools, drills, and dies for metalworking processes.
- General Machinery Parts: Used in manufacturing components such as shafts, bushings, levers, and brackets that require moderate strength and good formability.
- Automotive Parts: Suitable for automotive parts like crankshafts and connecting rods, where moderate strength and machinability are crucial for non-critical components.
