Depending on environmental conditions… media, operating temperature, working pressure, NACE application - standard CS valve body material can be made from (castings) WCB, WCC, LCC… or (forgings) A105, A350 LF2… You also have to consider SMYS for weld-end valves that will be welded to pipe-pups/pipeline.

Dear All,
Would like to discuss the selection of Valve casting materials for the Pipelines project meant for transportation of Liquids hydrocarbons and Gas,
The Pipe materials used are High strength steels of API 5L Gr. B X42,X52, X65 etc, depending on the requirement of licensor, How to get the correct casting materials for valves, The pressure and temp. Ratings are according to ASME B16.34.
