F5 is not a material code, it is a shape.
That's how it should be.

F5 and F4 mainly refer to the structure of the German standard gate valve
-
The valve F6 is made of martensitic stainless steel.
Martensitic stainless steel, which can adjust its mechanical properties through heat treatment, is a class of hardenable stainless steel. Typical grades are CR13 type, such as 2Cr13, 3Cr13, 4Cr13, etc. After quenching, the hardness is high, and different tempering temperatures have different combinations of strength and toughness, which are mainly used for steam turbine blades, tableware, and surgical instruments.
According to the difference in chemical composition, martensitic stainless steel can be divided into two categories: martensitic chromium steel and martensitic chromium-nickel steel. According to the different structure and strengthening mechanism, it can also be divided into martensitic stainless steel, martensitic and semi-austenitic (or semi-martensitic) precipitation hardening stainless steel and martensitic aging stainless steel.

The valve stem F6A corresponds to the national standard 1CR12 or 1CR13.
Stainless steel: 2Cr, Cr, Cr17Ni, Cr18Ni, 12Mo2Ti and other materials are generally selected. 2Cr CR13 stainless steel is suitable for water, steam and weakly corrosive media with nominal pressure less than or equal to 32MPa and temperature less than or equal to 450 degrees, and the surface can be strengthened by chrome plating, high-frequency quenching and other methods. 1CR17Ni2 stainless steel valve, cryogenic valve, can resist corrosive media.
1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti stainless acid-resistant steel are used in high-temperature valves with nominal pressure less than or equal to 600 degrees, and can also be used in stainless steel valves and cryogenic valves with a temperature less than or equal to -100 degrees. 1Cr18Ni9Ti can resist corrosive media such as nitric acid; 1Cr18Ni12Mo2Ti can resist corrosive media such as acetic acid. When 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti are used in high-temperature valves, nitriding treatment can be used to improve the anti-abrasion performance.

1. The F6A of the goal ball valve belongs to forged low alloy or stainless steel alloy in terms of material, which is the corresponding code name in the United States.
2. There are generally two models corresponding to this material in China, specifically 1Cr13 and 2Cr13.
-
It is what we commonly call the CR series stainless iron material.
However, they are generally 1cr13 and 2cr13
-
It is a forged low-alloy or stainless steel pipe fitting used in the high-pressure system in the United States.
Corresponds to 1cr12 or 1cr13 of the national standard.

F51 is a duplex stainless steel with twice the strength of austenitic stainless steel.
Chemical Composition: C Mn Si P s Cr NiShanghai Xiangqia metal team, looking forward to your consultation!
Duplex stainless steel composed of 21% chromium, molybdenum and nickel-nitrogen alloys. It has high strength, good impact toughness, and good overall and local resistance to stress corrosion. Duplex stainless steels have twice the yield strength of austenitic stainless steels, a feature that allows designers to reduce weight when designing products, giving this alloy an advantage over 316,317L.
This alloy is particularly suitable for temperatures ranging from -50°F to +600°F. This alloy can also be considered for applications beyond this temperature range, but there are some limitations, especially when applied to welded structures.
Duplex stainless steel has twice the compressive strength compared to austenitic stainless steel, and designers can reduce its weight compared to 316L and 317L. Alloy 2205 is particularly suitable for the -50°F +600°F temperature range and can also be used at lower temperatures in tightly restricted situations, especially for welded structures.
Applications:
Pressure vessels, high-pressure storage tanks, high-pressure pipes, heat exchangers (chemical processing industry).
Oil and gas pipelines, heat exchanger fittings.
Sewage treatment system.
Pulp and paper industry sorters, bleaching equipment, storage and handling systems.
Rotary shafts, press rolls, blades, impellers, etc. in high-strength and corrosion-resistant environments.
Cargo boxes for ships or trucks.
Food processing equipment.

F51 is a duplex stainless steel forging grade.
The corresponding pipe and plate grade is S31803, and the hardness of S31803 is less than HB293 in the standard of pipe SA312 and plate SA240. At lower C contents, the CR content is 18% to 28% and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, N.
Compared with ferrite, this kind of steel has the characteristics of austenitic and ferritic stainless steel, higher plasticity, toughness, no brittleness at room temperature, significant improvement in intergranular corrosion resistance and welding performance, and also maintains the 475 brittleness and high thermal conductivity of ferritic stainless steel, with superplasticity and other characteristics. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular by-product and chloride stress corrosion. Duplex stainless steel has excellent resistance to pitting and corrosion, and it is also a nickel-saving stainless steel.
It is mainly used in the production of acid oil and gas wells.

I can only say that this is impossible, you may read the kind of roadside magazine tabloid or something, because you send it with a mobile phone, there is no condition to copy the data, just give a few characteristics to compare, radar, from the electronic equipment, China is a horse can not catch up with the United States, the second generation aircraft and the fourth generation aircraft are even more incomparable, that is to say, the F22 will definitely be able to detect the J-8 early, plus the F22's stealth ability ......Medium-range air combat is basically one-sided, and the J-8 does not seem to be equipped with Thunderbolt 10 missiles, that is to say, it does not have over-the-horizon combat capabilities at all, so it is only beaten and does not fight back. Entering close combat, the F22 with supersonic cruise capability can definitely enter a good position earlier than the J-8, equipped with a vector nozzle engine and the F22 with a good aerodynamic shape has better maneuverability than the J-8 with a high-altitude and high-speed volley design concept, and will definitely be equipped with a helmet aiming system with AIM-9X, a missile with an off-axis angle of 90 degrees, that is to say, you don't need to put the nose of the aircraft at you when launching,. To sum up, what do you think are the chances of J-8 winning F22. >>>More
