About Stainless Steel
Strength, corrosion resistance, and surface quality for long-life components.
Stainless steel offers a useful combination of strength, corrosion resistance, and surface quality. It is selected for parts exposed to moisture, chemicals, cleaning cycles, or repeated mechanical loads.
303 improves machinability, 304 is broadly versatile, 316L adds chloride resistance, and precipitation-hardening grades such as 17-4 PH support higher-strength requirements.

Comparison of Common Stainless Steel Alloys
A scannable overview for early material selection.
Final selection should be confirmed against the drawing, service environment, stock condition, finish, and documentation requirements.
Coordinate material, machining, and passivation early
Share the service environment and drawing requirements so the process plan protects critical surfaces.
Characteristics of CNC Machining Stainless Steel
Heat, work hardening, tool engagement, and setup rigidity must be managed together.
Workholding and Rigidity
Control heat and tool engagement to reduce work hardening.
Cutting Heat Control
Use rigid setups for deep pockets, thin walls, and long shafts.
Finishing Allowance
Define passivation or electropolishing requirements on the drawing.
Inspection Strategy
Review thread class and galling risk for stainless assemblies.

CNC Machining Stainless Steel FAQs
Material, tolerance, finish, and production questions answered clearly.
What is the difference between 304 and 316L?
316L includes molybdenum for improved resistance in chloride and marine environments, while 304 is a versatile general-purpose grade.
Why use 303 stainless steel?
303 is selected when machining speed and chip control are priorities and the corrosion requirement is moderate.
Do stainless parts need passivation?
Passivation is often specified to remove free iron contamination and support the natural protective oxide layer.
