The stainless steel hydraulic fittings are made of 304 stainless steel and 316 stainless steel hex bars. The stainless steel fittings will be cut, CNC machined, and CNC drilled. As stainless steel is a anti-rust steel, it is widely used in hydraulic pipes. Stainless steel is a kind of hard raw material. It is hard to have good surface. But when using special blade, the surface of workpiece can reach Ra 0.4. So Ra 0.8, and Ra 1.6 easily reaches for special stainless steel CNC machining manurfacturer.
