Machining notes
Stainless steel often requires more deliberate tool strategy and heat management than aluminum.
Cycle time and tool wear can be higher, so critical tolerances should be identified early.
Surface finish expectations matter because visible stainless parts often carry a higher quality perception.

FAQ
Common questions about this CNC material.
Why choose stainless steel for CNC machining?
Stainless steel is a strong choice when the part needs corrosion resistance, durability, and reliable performance in demanding environments.
Is stainless steel harder to machine than aluminum?
Yes. It generally machines more slowly, creates more tool wear, and benefits from more careful planning than aluminum.
Which stainless grades are common?
303, 304, 316, and 17-4PH are commonly selected depending on machining ease, corrosion requirements, and strength targets.
