Dear all,

While doing valve material selection for a sour service piping, the material recommended by the client for 3/4" to 10" Ball valves(body) is duplex high alloy austentic stainless steel.
I have some doubt regarding this material...as per my knowledge duplex stainless steel itself has austentic as a part of it.and what exactly is meant by high alloy and dupplex ausentic stainless steel


since the material is given for valve size upto 10"...wat material can i chose for higher sizes upto 36
