Stainless steel IC (Investment Casting) fittings are precision-made plumbing and industrial components. They typically follow ASTM, ASME, and ISO standards. Common material grades include SS 304 (CF8) and SS 316 (CF8M), featuring BSP or NPT threaded connections and pressure ratings up to 150# to 300# class. Material and Manufacturing • Manufacturing Process: Investment casting (lost-wax process) for smooth finishes and tight tolerances. • Material Grades: SS 304 / CF8, SS 304L / CF3, SS 316 / CF8M, and SS 316L / CF3M. • Casting Standard: Conforms to ASTM A351 / ASME A351 specifications. Dimensions and Ratings • Size Range: 1/8' to 4' (DN6 to DN100) or larger on request. • Pressure Class: 150# heavy-duty or working pressures up to 1000 PSI depending on size and application. • Temperature Range: -20°C to 220°C (varies by grade and seal/thread type). Types of Fittings and Connections • Available Shapes: Elbow (90° / 45°), Tee, Cross, Union, Hex Nipple, Coupling/Socket, Reducing Bushing, and Cap. • Thread Types: BSP (British Standard Pipe), NPT (National Pipe Thread), or Socket Weld. • Surface Finish: Electro-polished, matte, or natural tumbled finish. If you need specifications for a specific type of fitting (such as an elbow or hex nipple) or a particular size and grade, let me know and I can provide those exact dimensions.
