The following is a list of stainless steels commonly used in valve construction. This list includes types of stainless steels as well as cross references of equivalent types of cast and forged stainless steel grades covering ASTM and EN, and valve standards associated to them.

Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.

Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe. The most common type of ball valve has a “free floating” design, so the trunnion type is a design change.
