It is widely used for applications requiring better mechanical properties and wear resistance. Our advanced CNC machining capabilities enable us to produce 1045 steel parts with tight tolerances of ±0.005mm and excellent surface finishes. 1045 steel responds well to heat treatment, allowing us to achieve various hardness levels through quenching and tempering processes. We offer comprehensive surface treatment options including polishing, black oxide coating, and various plating options to enhance corrosion resistance and performance. We provide complete manufacturing solutions from prototype development through high-volume production. Our engineering team offers expert DFM (Design for Manufacturing) support to optimize your designs for 1045 steel machining, ensuring cost-effective production while meeting stringent quality requirements. With our China factory and efficient logistics, we can deliver your precision components quickly and reliably. ## Technical Specifications | Material Grade | 1045 Medium Carbon Steel (UNS G10450) | Process | CNC Milling, CNC Turning, 5-Axis Machining | Tolerance | ±0.005mm (±0.0002") | Surface Finish | Polished (Ra 1.6), Black Oxide, Zinc Plated | Size Range | Up to 500mm diameter | Lead Time | 7-14 days (standard), 5-7 days (express) | MOQ | 10 pieces (prototypes), 100 pieces (production) | Certifications | ISO 9001, IATF 16949, ISO 14001 ## 1045 Steel Properties ### High Strength 1045 steel offers higher tensile and yield strength compared to low carbon steels.
