Stainless Steel CNC Machining Cost

Stainless steel is chosen for corrosion resistance, strength, and appearance. It generally machines slower than aluminum and can increase tooling and cycle time.

Alloy differences

303 is often easier to machine than 304. 316 offers stronger corrosion resistance but may be more challenging. Hardened stainless grades can increase cost further.

Work hardening

Some stainless steels work harden during cutting. Shops may use sharp tooling, proper coolant, and conservative strategies to maintain quality.

Finishing and passivation

Passivation, polishing, and electropolishing may be required for corrosion resistance or clean appearance. Include these details in your quote request.
