Global buyers seeking S45C carbon steel shafts want a supplier who can translate a concept into a reliable, cost-efficient part. S45C is a medium-carbon steel (~0.45% C) with good machinability, solid strength, and a finish that responds well to tempering. Finished shafts typically achieve tensile strength around 570–700 MPa; hardness is adjustable to suit drive or transmission needs. From concept to delivery, price depends on diameter and length, tolerances, surface finish, heat treatment, and required certifications. Design choices—standard sizes, straightness, runout, and balance—often cut costs. Provide a clear drawing or spec (DIN/ISO/JIS as relevant), tolerance, finish, and testing needs (hardness, NDT), plus packaging and shipping terms. With traceability and QA documentation, you can secure a reliable worldwide supply and minimize risk.
