This product provides SAE1045/S45C hot-rolled carbon steel round bars in large stock at competitive prices. SAE1045 (equivalent to JIS S45C) is a medium-carbon steel grade known for its high strength, machinability, and versatility in industrial applications. These round bars are manufactured through hot-rolling processes, ensuring consistent quality and suitability for machining, forging, or heat treatment.
Material Properties
SAE1045/S45C: Medium carbon content (~0.45%) balances strength, hardness, and ductility.
Excellent machinability and weldability; responds well to heat treatment (e.g., quenching and tempering) for enhanced surface hardness.
Mechanical Performance
High tensile strength (≥ 585 MPa) and wear resistance, ideal for load-bearing components.
Uniform microstructure from hot-rolling ensures dimensional stability and reduced internal stresses.
Standards & Compliance
Conforms to SAE J403, JIS G4051, and ASTM A29 standards for chemical composition and mechanical properties.
Cost-Efficiency
Bulk availability reduces lead times; competitively priced for budget-conscious projects.
Versatility
Available in various diameters (customizable lengths) with optional surface finishes (e.g., black, turned, or polished).
Machinery Components: Gears, shafts, bolts, and couplings requiring high strength and wear resistance.
Automotive Parts: Axles, crankshafts, and suspension components.
Tool Manufacturing: Dies, molds, and tool holders.
Construction: Structural supports, fasteners, and heavy-duty hardware.
Agricultural Equipment: Plowshares, tractor parts, and harvesting machinery.
General Manufacturing: Industrial rollers, hydraulic components, and machinery frames.
