Frequently Asked Questions About CNC Stainless Steel Parts
Common questions about stainless steel CNC machining, material grades, tolerances, surface finishing and custom part manufacturing.
What stainless steel grades can CNCTAL machine?
CNCTAL can machine common stainless steel grades including 304, 316, 303 and 17-4PH. We can also review other stainless steel materials based on your drawing, application environment and strength requirements.
What is the difference between 304 and 316 stainless steel?
304 stainless steel is a common general-purpose grade with good corrosion resistance. 316 stainless steel provides better corrosion resistance, especially for marine, fluid, chemical and medical-related applications.
Is stainless steel difficult to CNC machine?
Stainless steel is generally more difficult to machine than aluminum because it is tougher, generates more heat and can work-harden during cutting. Proper tooling, cutting parameters and inspection control are important for stable quality.
Can you make stainless steel liquid cooling connectors?
Yes. CNCTAL can manufacture stainless steel fittings, threaded connectors, manifolds and liquid cooling components. For parts with internal cross-holes or sealing surfaces, please provide drawings with tolerance, roughness and deburring requirements.
What tolerance can you achieve for CNC stainless steel parts?
Depending on the part size, geometry, stainless steel grade and critical features, CNCTAL can support precision tolerance requirements up to ±0.01 mm. Critical dimensions should be clearly marked on the 2D drawing.
What surface finishes are available for stainless steel parts?
Stainless steel CNC parts can be supplied as-machined, passivated, polished, brushed, sandblasted or electropolished depending on appearance, corrosion resistance and functional surface requirements.
