Custom precision CNC machining 1020 steel from China
We are a specialized provider of custom CNC machining 1020 steel parts China. Our factory manufactures high-precision low-carbon steel components using advanced CNC milling, turning, and multi-axis machining centers. From prototype to full production runs, every part is machined to your exact specifications with consistent quality and dependable lead times.
What is 1020 Steel?
1020 steel is a widely used low-carbon (mild) steel containing approximately 0.20% carbon by weight. It offers an excellent balance of machinability, weldability, and formability, making it one of the most versatile materials for custom CNC machining 1020 steel parts China and worldwide.
With a tensile strength ranging from 420 to 550 MPa in the hot-rolled condition, and good case-hardening response, 1020 steel is ideal for parts that require moderate strength, tight dimensional control, and cost-effective production. It can be carburized, nitrided, or induction hardened to enhance surface wear resistance while maintaining a ductile core.
Our machining facility works exclusively with mill-certified 1020 steel stock, including hot-rolled, cold-drawn, and turned-and-polished bars in diameters from 6 mm to 250 mm. We also process 1020 steel plates, blocks, and custom-cut blanks for larger components. Every order is tailored to meet your exact part specifications and tolerance requirements.
1020 Steel — Nominal Chemical Composition
| Element | Weight % |
|---|---|
| Carbon (C) | 0.17 – 0.23 |
| Manganese (Mn) | 0.30 – 0.60 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.050 |
| Iron (Fe) | Balance |
CNC Machining Capabilities for 1020 Steel
Every process is optimized for low-carbon steel to deliver superior surface finish, tight tolerances, and repeatable accuracy for custom CNC machining 1020 steel parts China clients trust.
CNC Milling
3-axis, 4-axis, and 5-axis milling of complex geometries including slots, pockets, contours, and 3D surfaces. Capable of machining parts up to 1,500 mm × 800 mm × 600 mm.
CNC Turning
Precision turning of shafts, bushings, pins, and cylindrical components with diameters from 3 mm to 300 mm. Live tooling enables milling and drilling in a single setup.
Tight Tolerances
Standard machining tolerance of ±0.01 mm, with achievable precision down to ±0.005 mm on critical features. Full dimensional inspection reports provided with every order.
Complex Geometries
Multi-axis machining of undercuts, angled holes, deep cavities, thin walls, and intricate profiles that would be impossible with conventional 2-axis equipment.
Prototype to Production
Rapid prototyping in as little as 3–5 business days. Seamless transition to low-volume (1–50 pcs) and medium-volume (50–5,000 pcs) production batches without tooling changes.
Surface Finishing
As-machined, bead blasting, zinc plating, nickel plating, black oxide, powder coating, and polishing to achieve your desired surface quality for 1020 steel parts.
Secondary Operations
Thread tapping, reaming, broaching, knurling, grooving, cross-drilling, and deburring — all performed in-house to reduce supply chain complexity and shorten delivery times.
Quality Inspection
In-process and final inspection using calibrated instruments: CMM, profilometer, hardness tester, micrometer set, and optical comparator. 100% dimensional verification on critical features.
