Alloy Steel F9 Ball Valve
F9 (EN 1.7386) is a high-chromium, molybdenum (9% Cr - 1% Mo) heat-resistant alloy steel. F9 valves are specifically designed for high-temperature, high-pressure environments, exhibiting excellent creep resistance, oxidation resistance, crack resistance, and a low thermal expansion rate.
① F9 valves contain 9% Cr, therefore their resistance to high-temperature H₂S sulfide corrosion is far superior to F5 and F22;
② F9 valves have a high silicon content, enabling the formation of a dense, high-temperature oxide film, making them suitable for high-temperature sulfur environments such as furnace outlets;
F9 valves meet the high-parameter hydrogen-critical conditions of the Nelson curve, exhibiting superior resistance to hydrogen embrittlement and hydrogen-induced cracking compared to F22, making them suitable for high-temperature hydrogenation units.
① The creep strength of F9 valves decreases significantly at temperatures >590℃, and their endurance strength at the same temperature is significantly lower than that of F91 valves, making them unsuitable for supercritical main steam pipelines;
② F9 valves prioritize resistance to sulfidation, while F91 valves prioritize creep strength under pure steam conditions;
① F9 valves can be hardened in air, and the heat-affected zone after welding easily forms hard and brittle martensite;
② Preheating before welding and post-weld PWHT are absolutely essential for F9 valves.
① Heating furnace outlet manifold, oil transfer line;
② High-temperature oil and gas + H₂S sulfidation environment (most typical scenario for F9 valves);
③ When F22/F5 valves are insufficient for sulfidation resistance, F9 valves are selected;
Hydrocracking, hydrodesulfurization high-temperature loops, reactor inlet and outlet bypass lines, heating furnace section (F91 valves are preferred for pure high-temperature main steam operation, F9 valves are not used);
Subcritical boiler superheaters and reheaters;
High-temperature cracked oil and gas, oxidation + sulfidation coexisting conditions.
① Resistance to high-temperature sulfide corrosion;
② High-temperature, high-pressure hydrogen-containing process oil-gas mixtures containing hydrogen sulfide (H₂S);
① Pure steam media with ultra-high creep strength;
② Supercritical thermal power systems.
