XM19 vs SS316 & SS316L for stems in gate valves

XM19 vs SS316 & SS316L for stems in gate valves

(OP)
Do XM19 stems are more superior than SS316 & SS316L. we are having a requirement for fertilizer plant for urea application.

RE: XM19 vs SS316 & SS316L for stems in gate valves

Nitronic 50 (S20910) will have slightly better corrosion resistance than 316L, and it is often used in the cold worked condition at high strength. These alloys also have superior galling resistance, I would prefer Nit50.
