Milling Parts

 

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 304/304LStainless steel 304L (CNC) has excellent mechanical properties and good machinability. Resistant to most environments and corrosive media.
Stainless steel 316/316LStainless steel 316L (CNC) has similar mechanical properties to 304, with higher corrosion and chemical resistance. Ideal for marine applications.
Stainless steel 303Stainless 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 PHStainless 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 416Stainless steel 416 is magnetic and has a high machinability.
Stainless steel 2205 DuplexStainless 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 420Stainless steel 420 provides high strength and corrosion resistance. It is the hardest of all stainless steels when hardened.
Stainless steel 440CStainless steel 440C has improved toughness and corrosion resistance due to Carbon and Chromium content.
Stainless steel 430Stainless steel 430 is magnetic and corrosion resistant.
Stainless steel 301Stainless steel 301 is corrosion resistant similar to Stainless steel 304.
Stainless steel 15-5Stainless 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. How much do CNC machining materials cost?

 

The diverse range of materials available for CNC machining introduces variability in costs,

influenced by both the specific material properties and overall characteristics.

When opting for metal parts, Aluminum 6061 emerges as a cost-effective choice.

For budget-conscious projects, ABS stands out as the most economical option.

It's essential to note that machining difficulty plays a crucial role in cost determination.

Materials like stainless steel, being harder than aluminum, pose greater machining challenges,

leading to an escalation in overall costs.

 

2. What's the general surface texture of CNC milled and turned parts?

 

The surface texture of machined milled parts is commonly around 3.2μm (or 1.6μm for more

recent machines). In the case of turned parts, a finer surface finish is achieved, reaching a

roughness of 0.8μm.

Notably, this enhanced surface texture in turning is accomplished without the necessity of

adjusting machining speeds.

 

3. What are your tolerances for machined parts?

 

Our machined parts adhere to precision standards, featuring +.005”/- .005” local tolerances

across most metal geometries and +/- 0.010" for plastics.

It's worth noting that tolerances may vary for larger parts, especially with considerations for

flatness post heat treatment.

 

An "As Milled" finish for CNC parts requires a minimum surface finish of 125. Fabricated parts

maintain a 0.010” dimensional tolerance and a 1° angular tolerance.

 

Tapped holes not explicitly labeled as features in the CAD model may be machined based on

the specified diameters. Crucially, surface treatments such as anodizing, bead blasting,

iriditing, powder coating, etc., will only be applied upon explicit payment and acknowledgment.

 

4. Why choose CNC machining?

 

The decision to leverage CNC machining is driven by its attributes of speed, accuracy, and

versatility. This manufacturing solution excels in delivering end-use parts across different

volumes with notable efficiency, eliminating the need for substantial investments in hard tooling

or intricate set-ups.
