What is the material of valve stem F6A?
1, the ball valve F6A in the material belongs to forged low alloy or stainless steel alloy, this is the United States corresponding code.2, China this material corresponds to the model generally has two kinds, specific for 1CR13 and 2CR13.
Forged low alloy or stainless steel fittings for American high pressure systems.Corresponds to the national standard of 1Cr12 or 1Cr13.
Is what we commonly called "CR" series of stainless iron materialBut generally they are 1CR13 and 2CR13~~~
The valve stem F6A corresponds to the national standard 1Cr12 or 1Cr13.Stainless steel generally choose 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr18Ni12Mo2Ti and other materials. 2Cr13, 3Cr13 stainless steel for nominal pressure less than 32MPa, the temperature is less than or equal to 450 degrees of water, steam and weak corrosive medium, can be chromium plating, high frequency hardening and other methods to strengthen the surface. 1Cr17Ni2 stainless steel valves and cryogenic valves are resistant to corrosive media. 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti stainless acid resistant steel for nominal pressure less than 6.4MPa, temperature is less than or equal to 600 degrees of high temperature valve, can also be used for temperature less than -100 degrees of stainless steel valve, low temperature valve. 1Cr18Ni9Ti can resist corrosive medium such as nitric acid; 1Cr18Ni12Mo2Ti can resist corrosive medium such as acetic acid. When 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti are used in high temperature valves, nitriding treatment can be adopted to improve the scratch resistance.
