F317L ball valve，Special material ball valve

The 317L stainless steel ball valve adopts an upper-mounted structure. The high pressure reduces the connection bolts of the valve body, enhancing the reliability of the valve and overcoming the influence of the system's own weight on the normal operation of the valve. The 317L ball valve is widely used in pipelines for coal chemical industry, petrochemical industry, rubber, papermaking, pharmaceuticals, etc., as a device for splitting and merging media or changing the flow direction. Due to its dual-phase structure of austenite + ferrite, and the content of both phases being basically equal, the 317L has the characteristics of both austenite stainless steel and ferrite stainless steel. The yield strength can reach 400Mpa to 550MPa, which is twice that of ordinary austenite stainless steel.

The F317L ball valve is a stainless steel ball valve with a shell and internal components cast, forged or rolled using materials such as ASTM A182 Gt F317L or UNS S31703. It features high resistance to intergranular corrosion and pitting corrosion. This valve is made of high-grade ultra-low carbon austenitic stainless steel, equivalent to the national standard grade 022Cr19N/13Mo3. Its main components include carbon (C) 0.030, manganese (Mn) 2.00, phosphorus (P) 0.045, sulfur (S) 0.030, silicon (Si) 1.00, nickel (N) 11.0 - 15.0, molybdenum (Mo) 3.0 - 4.0, and chromium (Cr) 18.0 - 20.0. Compared to conventional chromium-nickel austenitic stainless steel, it not only has stronger resistance to chemical corrosion, but also has higher ductility, resistance to stress corrosion cracking, pressure resistance and high-temperature performance. Its intergranular corrosion resistance is better than that of 317 steel, and its resistance to pitting corrosion and stress corrosion is superior to 316. This product has excellent corrosion resistance, heat resistance, low-temperature strength and mechanical properties, making it particularly suitable for installation in industrial pipeline transportation systems in petrochemical, fertilizer, papermaking, printing and dyeing, food and related industries, to cut off or connect the medium inside the pipe.

The 317L ball valve is widely used in pipelines for coal chemical, petrochemical, rubber, papermaking, pharmaceutical and other industries as a device for splitting and merging the medium flow or changing the flow direction. Due to its dual-phase structure of austenite and ferrite, and the fact that the content of both phases is basically the same, the 317L combines the characteristics of austenitic stainless steel and ferritic stainless steel. Its yield strength can reach 400Mpa to 550MPa, which is twice that of ordinary austenitic stainless steel.
