The corrosion resistance issue of Stellite
Thread Content
Valve for liquid chlorine flow; liquid chlorine is purchased externally, and its water content is uncertain. Is it okay to use a 316L valve body for the control valve, and H.C. components for the valve spool, seat, and diaphragm? The equipment side has proposed using STL cladding for the valve core and seat; if the moisture content in liquid chlorine is high, will Stellite be resistant to corrosion in such conditions?
No, chloride ions can cause corrosion of Stellite. A senior official in a certain organization once said that high levels of chloride ions in water eventually lead to corrosion of Stellite through butt welding
