Part CNC Service
In a broader sense, CNC machining generates components with precise tolerances and impressive
material properties. It is well-suited for individual tasks and low-to-medium volume production
(up to 1,000 parts) due to its high repeatability. However, it does impose more design constraints
compared to 3D printing, primarily due to its subtractive nature.
Product Details
Stainless steel is highly resistant to corrosion and rust, making it suitable for situations
where a part may be exposed to the elements for a long period of time. Stainless steel is also
fairly malleable and ductile.
| Common Stainless Steel Materials |
| No. | Properties |
| Stainless steel 304/304L | Stainless steel 304L (CNC) has excellent mechanical properties and good machinability. Resistant to most environments and corrosive media. |
| Stainless steel 316/316L | Stainless steel 316L (CNC) has similar mechanical properties to 304, with higher corrosion and chemical resistance. Ideal for marine applications. |
| Stainless steel 303 | Stainless steel 303 (CNC) has excellent toughness, but lower corrosion resistance than 304. Ideal for high volumes, due to its excellent machinability. |
| Stainless Steel 17-4 PH | Stainless steel 17-4 (CNC) - SAE grade 630 - is a precipitation hardening alloy with good corrosion resistance. Can be hardened up to 44 HRC. |
| Stainless steel 416 | Stainless steel 416 is magnetic and has a high machinability. |
| Stainless steel 2205 Duplex | Stainless steel 2205 Duplex (CNC) is the alloy with the highest strength and hardness. Suitable for applications in severe environments up to 300°C. |
| Stainless steel 420 | Stainless steel 420 provides high strength and corrosion resistance. It is the hardest of all stainless steels when hardened. |
| Stainless steel 440C | Stainless steel 440C has improved toughness and corrosion resistance due to Carbon and Chromium content. |
| Stainless steel 430 | Stainless steel 430 is magnetic and corrosion resistant. |
| Stainless steel 301 | Stainless steel 301 is corrosion resistant similar to Stainless steel 304. |
| Stainless steel 15-5 | Stainless steel 15-5 has a higher toughness than 17-4, better corrosion resistance and transverse properties compared to other similar martensitic grades. |
Stainless Steel Finishing and Post-Processing
The finish of stainless steel can vary significantly depending on the surface roughness.
However, it is typically described as shinier compared to unfinished aluminum alloys,
and it tends to have a slightly darker and more silver color.
Stainless steel offers flexibility in achieving various surface finishes, including options such as
media blasting, sanding, hand-polishing, and powder coating.
These processes can be employed to achieve a wide range of surface finish textures and
appearances.
| Name | Machining Marks |
| Brushed + electropolishing | Removed on Primary surfaces |
| Electroless nickel plating | Reduced but visible |
| As machined | Visible, light surface scratches |
| Smooth machining | Visible, light surface scratches |
| Fine machining | Slightly visible |
| Polishing | Removed on primary surfaces |
| Bead blasting | Removed for non-cosmetic, removed on primary surfaces for cosmetic |
| Brushing | Reduced for non-cosmetic, removed on primary surfaces for cosmetic |
| Powder coating | Removed |
| Black oxide | Visible |

FAQ's
1. How can I ensure my design is confidential?
We prioritize the confidentiality of your design, and to reinforce this commitment, we are willing
to enter into a Non-disclosure Agreement (NDA) with our customers.
This agreement can be established prior to the quoting phase or when placing an order, ensuring
a secure environment for your proprietary information.
2. Can make design drawings for me?
Regrettably, we don't offer a dedicated product design service. Nevertheless, we conduct thorough
Design for Manufacturing reviews for all approved orders.
Our collaborative approach involves assisting clients in refining their 2D and 3D drawings to
enhance manufacturability, resolve design conflicts, and cut down on production costs.
Explore our recommendations for preparing CAD drawings for manufacturing.
3. How does compare to other suppliers on price?
Unlike Chinese suppliers who often compete on price, We chooses a different approach.
While our prices may not be the lowest, we prioritize delivering the highest levels of quality,
rapid response, and professional results, setting us apart in the market.
4. How quickly can I get my parts?
For quality parts, a turnaround time of as little as two weeks is possible when complete 2D and 3D
CAD models are provided. Parts with more complexity or special features may take longer.
To obtain precise lead times for your project, request a quote.
In terms of shipping, the majority of our shipments use air freight, ensuring delivery within a few
days from China to Europe or North America.
