CNC machining is a subtractive manufacturing process that automates the removal of material
from raw stock using computer-generated instructions.
Typically, CNC machines fall into two categories: those that keep the raw stock stationary while
the cutting tool rotates, and those that rotate the raw stock while moving it against a stationary
tool. Various machines incorporate these principles in different ways, often combining them to
create intricate parts with complex features.
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.

CNC Machining Applications
CNC machining finds extensive applications across various industries. It is prevalent in sectors
like aerospace, automotive, consumer electronics, robotics, agriculture, and others that rely on
metal components.
Additionally, CNC machining plays a significant role in medical devices, household products,
energy, oil and gas, as well as various consumer-oriented applications.
It stands as one of the most widely adopted manufacturing processes globally.

FAQ's
1. The Best Stainless Steel Grades for CNC Machining
When it comes to CNC machining, there are four primary stainless steel grades that stand out:
430F Stainless Steel: This grade is popular in machining industries due to its excellent feeds
and speeds. It falls under the ferritic category and is similar to 430 stainless steel but contains
increased sulfur to enhance machinability.
300 Series Stainless Steel: Among the most widely used grades, 303 Stainless Steel is
particularly fast to machine. It offers good corrosion resistance, making it suitable for various
industrial machining parts like screws, nuts, bolts, gears, and shafts. It is also easily modifiable.
Nitronic 60: This stainless steel grade boasts superior wear and corrosion resistance, making it
a versatile choice. It has a yield strength almost double that of 304 stainless steel and
exceptional oxidation resistance. Common applications include valve stems, fasteners, pins,
seats, shafts, rings, bushings, and bearings.
17-4 PH Stainless Steel: Renowned for its high corrosion resistance and strength, 17-4 PH
Stainless Steel retains its durability even at high temperatures. The "PH" in its name stands for
"precipitation-hardened," signifying a treatment that increases its yield strength.
This grade is magnetic and can be heat-treated for added hardness.
3. How thin can you machine stainless steel?
CNC machining thin stainless steel components requires special attention.
The minimum thickness for metals should not go below 0.5mm. To optimize cost and machining
efficiency, it is advisable to increase the thickness of thin components to at least 0.8mm.
Thicker walls provide added stability and cost savings, except when weight is a critical
consideration. Thin features are more susceptible to vibration, which adds complexity
and significantly extends machining time.
4. What if I am not fully satisfied with the received parts?
We stand by the quality of our materials and workmanship, adhering to the terms outlined in
the original order and the information provided by you.
If there are any disputes arising from subjective judgments, we encourage you to bring them
to our management's attention. We are committed to working in good faith to ensure your
