1045 Steel Bar Hot Rolled Steel Round Bar 1045 Steel Round Bar Carbon Steel Round Bars
AISI 1045 Steel round bar belongs to high carbon steel under american standard. AISI 1045 is also a quenching and tempering steel, which owns high strength. AISI 1045 alloy steel can be produced into hot rolled round bars and square bars, cold-drawing bars,forged bars. We henan bebon can supply AISI 1045 all of shapes.
AISI 1045 round bar is widely used for manufacturing moving parts which needs high strength, such as plunger of air compressor and pump, rolled shaft, connecting rod, endless screw, gear rack, dowel of heavy machines. AISI 1045 round bar is often used in quenching and tempering and normalizing delivery state . After high-frequency quenching or shorterizing, AISI 1045 round bar can be applied to produce wear resistant parts, such as crank axle, machine tool shaft,transmission shaft and so on.
Cold Roll Steel Round Bar/Rod 1045 is normally used for industrial, machine, and tool applications. 1045 is a commonly used low carbon steel alloy with good strength, ductility, and ease of machining. 1045 stock is available in full size and custom cut lengths. AISI 1045 Carbon Steel

SAE-AISI 1045 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1045 is the designation in both the SAE and AISI systems for this material. G10450 is the UNS number. It can have a moderately high tensile strength among the wrought carbon or non-alloy steels in the database. The properties of SAE-AISI 1045 steel include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare SAE-AISI 1045 steel to: wrought carbon or non-alloy steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
Product Applications
Hot rolled SAE-AISI 1045 is SAE-AISI 1045 steel in the hot worked condition. It has the lowest strength and highest ductility compared to the other variants of SAE-AISI 1045 steel.
