Stainless Steel Valve Stem

Stainless steel valve stems are generally made of materials such as 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr18Ni12Mo2Ti, etc. 2Cr13 and 3Cr13 stainless steel are suitable for water, steam, and weakly corrosive media with a nominal pressure of 32MPa and a temperature of 450. The surface can be chrome plated and strengthened by high-frequency quenching. 1Cr17Ni2 stainless steel valves and low-temperature valves are resistant to corrosive media. 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti stainless steel and acid resistant steel are used for high-temperature valves with nominal pressure less than or equal to 6.4MPa and temperature less than or equal to 600 degrees, as well as stainless steel valves and low-temperature valves with 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 using 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti for high-temperature valves, nitriding treatment can be used to improve abrasion resistance.
