2. Stainless Steel Casting: Process, Technology & Specifications

Stainless Steel Casting Process Flow

1. Pattern Design & Molding → CAD/CAM modeling, wax or resin patterns.
2. Investment Coating → Multilayer ceramic shell building for precision.
3. Dewaxing → Steam autoclave removes wax pattern.
4. Metal Pouring → Molten stainless steel (grades: 304, 316, 420, 17-4PH) is cast.
5. Knockout & Cleaning → Shell removal, shot blasting for clean finish.
6. CNC Machining & Inspection → Precision finishing; 100% dimension and metallography check (ISO 8062 CT4-CT7 tolerance).
7. Surface Finishing & QA → Passivation, polishing, NDT (Ultrasonic, X-ray), and packaging.

Certified to ISO 9001:2015, ANSI B16.34, and RoHS standards. Typical product lifespan >20 years under corrosive outdoor exposure.
