AISI 1045 Steel Round Bar Sheet Plate
AISI 1045 steel is a medium carbon steel that has excellent tensile strength and hardness. It is commonly used in applications where stress and strain are present, such as gears, axles, crankshafts, and machinery parts.
Round Bar: AISI 1045 steel round bars have a diameter of up to 500mm and are commonly used for shafts, bolts, and grinders. They come in hot rolled, cold drawn, and forged conditions.
Sheet: AISI 1045 steel sheets are available in different thicknesses and dimensions. They are commonly used for automotive parts, construction equipment, and machinery components.
Plate: AISI 1045 steel plates are typically available in thicknesses ranging from 6mm to 300mm. They are commonly used for mold base, machinery parts, and construction applications.
AISI 1045 steel can be further enhanced by heat treatment methods such as annealing, quenching, and tempering. Its machinability is good with reasonable welding properties. It is also popular in the fabrication industry due to its ease of manipulation and excellent ductility.
Below are the product specifications of AISI 1045 steel round rods, plates and plates:
