Stainless steel for CNC-machined corrosion-exposed fittings, housings and equipment interfaces. 303 favors machinability, while 304 and 316 are considered for different corrosion environments. Confirm the grade against the service conditions.
How should I select the grade?
303 favors machinability, while 304 and 316 are considered for different corrosion environments. Confirm the grade against the service conditions. Material availability, stock size and certificate requirements are confirmed during quotation; a listed grade is not a stock guarantee.
What affects machining and inspection?
Review chlorides, passivation, galling, machining work-hardening and cleaning requirements. Functional tolerances depend on part geometry, material condition, fixturing and measurement method, not only the material family.
What should I specify for finishing?
State the finish standard, thickness, color or texture, masking and functional surfaces. Consider coating build in fits and threads. Approve any material or finishing substitution in writing.
Material quotation checklist
Send the exact grade and condition, 2D drawing, STEP model, quantity, critical features, service environment and traceability requirements. Tecpreva can review machining suitability and proposed alternatives before production.
