stainless steel pipe fitting union
SS 304 is the most common austenitic steel and contains both chromium and nickel.
The 304 stainless steel union has excellent resistance to a wide range of atmospheric environments and many corrosive media. It is prone to pitting and crevice corrosion in warm chloride environments, stress corrosion cracking above about 60 ¡ãC, and is resistant to pitting corrosion in water containing chlorides up to about 400 mg/L at ambient temperature, It can be reduced to about 150 mg/L 60 degrees Celsius at ambient temperature. 304 stainless steel unions are used in a variety of domestic and industrial applications, such as food handling and processing equipment, chemical containers, including for transportation, heat exchangers, machine parts and automotive headers, construction areas, and more.
