Stainless steel is a recyclable alloy comprising iron, carbon,

and chromium (ranging from 11% to 18%).

This unique composition enhances its durability, elevates corrosion resistance, even at high

temperatures, and prevents rust formation.

Stainless steel exhibits remarkable strength, exceptional corrosion resistance, ease of cleaning

and sterilization, making it particularly valuable in medical equipment. It can withstand extreme

temperature conditions and is highly weldable.

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.

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 types of stainless steel can I machine?

We provide a selection of 11 distinct stainless steel options for your CNC-machined parts,

including Stainless Steel 304, Stainless Steel 316, Stainless Steel 303, Stainless Steel 17-4PH,

Stainless Steel 416, Stainless Steel 2205 Duplex, Stainless Steel 420, Stainless Steel 440C,

Stainless Steel 430, Stainless Steel 301, and Stainless Steel 15-5.

2. What is the best stainless steel 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.
