Sinbo Precision specializes in manufacturing 1018 steel CNC machined parts, offering high-quality low carbon steel components for a wide range of industrial applications. 1018 steel is one of the most commonly used cold-rolled steels, known for its excellent machinability, good weldability, and superior formability compared to A36 hot-rolled steel. Its low carbon content (0.15-0.20%) makes it ideal for applications requiring ease of machining and welding.
Our advanced CNC machining capabilities enable us to produce 1018 steel parts with tight tolerances of ±0.005mm and excellent surface finishes. We offer various surface treatment options including polishing, black oxide coating, and plating to enhance corrosion resistance and aesthetic appeal. 1018 steel is particularly suitable for parts that require subsequent heat treatment, carburizing, or case hardening processes.
We provide comprehensive manufacturing services from prototype development through high-volume production. Our engineering team offers expert DFM (Design for Manufacturing) support to optimize your designs for 1018 steel machining, ensuring cost-effective production without compromising quality. With our USA warehouse and fast delivery capabilities, we can meet your urgent production needs while maintaining competitive pricing.

1018 steel offers superior machinability with a machinability rating of 78% of B1112. Ideal for high-speed machining operations.
Excellent weldability characteristics with all common welding methods. Low carbon content minimizes cracking during welding.
Excellent formability for bending, stamping, and cold forming operations. Can be severely bent without cracking.
Can be case hardened through carburizing or nitriding processes. Suitable for applications requiring surface hardness.
One of the most economical steel grades available. Low material cost combined with excellent machinability reduces production costs.
Widely used across various industries for general purpose applications. Suitable for parts not requiring high strength.
Gears, shafts, bushings, pins, and general machinery parts requiring good machinability
Brackets, spacers, linkage components, and non-critical automotive structural parts
Bolts, nuts, screws, washers, and other fastening components for general applications
Frames, supports, brackets, and structural components for industrial machinery
Jigs, fixtures, tool holders, and precision tooling components for manufacturing
Handles, knobs, hinges, and general hardware components for various applications

Our minimum order quantity is 10 pieces for prototypes and 100 pieces for production runs. We can accommodate lower quantities for development projects with appropriate setup considerations.
Standard lead time is 5-10 days for 1018 steel CNC machined parts. Express service with 3-5 day turnaround is available for urgent projects. Lead times may vary based on complexity and quantity.
Yes, 1018 steel can be case hardened through carburizing or nitriding processes to increase surface hardness while maintaining a ductile core. It is not typically through-hardened due to its low carbon content.
We offer polished finishes (Ra 1.6 or better), black oxide coating for corrosion resistance and appearance, zinc plating, and various other surface treatments based on your application requirements.
1018 steel has lower carbon content (0.15-0.20%) compared to 1045 steel (0.43-0.50%), making 1018 more machinable and weldable but with lower strength and hardness. 1018 is ideal for parts requiring good machinability, while 1045 is better for higher strength applications.
