Stainless steel is a recyclable alloy consisting of iron, carbon, and chromium
(ranging from 11% to 18%). The inclusion of chromium enhances the steel's strength,
durability, and resistance to corrosion, particularly at elevated temperatures, preventing
rust formation.
Stainless steel exhibits exceptional strength, corrosion resistance, ease of cleaning,
and sterilization properties, making it highly suitable for applications such as medical equipment.
It can withstand extreme temperatures and is well-suited for welding processes.
Our CNC machining services empower you to fabricate bespoke stainless steel components
tailored to a wide array of applications in industries including energy, medical technology,
agriculture, industrial automation, machinery, robotics, and construction.
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 are standard machining tolerances?
The standard machining tolerance is ± 0.005" or 0.13mm, defining the acceptable range for a
dimension. If a CNC machining tool has a tolerance of ± 0.01 mm, it implies a deviation of
0.01 mm in each cut.
When accompanied by a drawing, our CNC machining service can achieve CNC parts with
tolerances as low as ± 0.0002 in. In the absence of a drawing, all CNC parts are produced
following our ISO 2768 medium standard.
Additionally, we have the capability to machine to tighter tolerances, such as ±0.025mm or
±0.001", when an engineering drawing specifies critical features.
2. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In cases where a specific fillet radius is not specified in the 3D model or drawing, fillet radii
suitable for easy machining will be added based on the machinist's judgment.
As a general guideline, internal vertical edge radii may exceed 1/3 of the depth, while internal
horizontal edges can either be left sharp or have a radius in the range of 0.5mm to 1mm.
Specific fillet requirements should be indicated if needed.
3. Dedication to Quality Assurance
Our commitment to customer trust is reflected in our rigorous adherence to proven quality
management principles. This commitment extends to enhancing customer satisfaction and
continuously improving our performance and capabilities.
With decades of experience, we meet stringent regulations and maintain PPAP compliance,
