CNC machining, standing for computer numerical control machining, is a prevalent manufacturing
process that employs automated, high-speed cutting tools to shape designs from metal or plastic
stock.
Standard CNC machines encompass 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
Variations exist in how CNC parts are cut, with possibilities such as the workpiece remaining
stationary while the tool moves, the tool staying in place while the workpiece is rotated and moved,
or both the cutting tool and workpiece moving together.
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.

FAQ's
1. What is your typical lead time? Can my parts be produced on a rush basis?
Our standard lead time for screw machine products, encompassing quoting, manufacturing,
and shipping, is typically around one week. With an on-time delivery rate exceeding 99%,
we prioritize efficiency. Depending on factors like tooling, gauges, and material availability,
we may have the capability to produce your parts on an expedited basis. Feel free to inquire!
2. What formats of the files can you accept?
We can accept most of the 3D file formats like SolidWorks (.sldprt)/ ProE(.prt) / IGES(.igs) /
STEP (.stp). We can also use 2D drawing (.pdf) or AutoCAD (.dwg) for quote against the parts
with simple structure. All the other files formats are not listed above but can be read in
AutoCAD/ProE/SolidWorks/ will be also fine for us.
3. How long does a quotation take?
Typically, we aim to respond to Requests for Quotation (RFQ) within a few days of receipt.
In the event of any delays, rest assured that we will promptly notify you of the situation.
4. How quickly can I get my parts?
We can produce quality parts in as little as two weeks if complete 2D and 3D CAD models are
provided. However, more intricate parts with special features may require additional time.
For more precise lead times based on your project, request a quote.
Regarding shipping, the majority of our shipments are via air freight, taking only a few days
from China to Europe or North America.
