Where can i get a copy of Daniel's standard metallurgy for orifice pates?
Daniel Measurement and Control offers orifice plates in two standard grades of stainless steel, 304SS and 316SS. Both plate materials are supplied/offered in accordance with the composition, properties and criteria described in ASTM A240 316SS and ASTM A240 304SS, which can be accessed publically via the internet or the published ASTM standards volumes.
