Gabriel Tube Fittings, a trusted manufacturer and supplier based in Cairo, Egypt, proudly presents its precision-engineered **Stainless Steel 347 Needle Valves**. These valves are crafted for accurate flow control and dependable shut-off, even in high-temperature and corrosive environments. They’re the go-to choice for instrumentation and process systems where precise fluid or gas regulation is a must. Built to last, Gabriel’s SS 347 needle valves ensure smooth operation, leak-tight sealing, and impressive resistance to thermal fatigue and chemical damage.
**Stainless Steel 347** is a niobium (columbium)-stabilized austenitic stainless steel that excels in resisting intergranular corrosion, particularly after welding or extended exposure to high temperatures. It maintains its strength and oxidation resistance at temperatures reaching up to 870°C, boasting a typical tensile strength of 515 MPa along with excellent creep and stress rupture properties. This makes SS 347 an outstanding choice for environments with thermal cycling and high-temperature media handling.
