Low Temperature Service???
Low Temperature Service???
(OP)
I am wondering what is the definition of "Low Temperature Service". For example, what is the max temperature that a ASTM A420 Grade WPL6 elbow can be used? How do the chemistry and mechanical properties differ from non-low temp service?
Thanks in advance

at -50 deg F, the minimum Charpy impact value is 13 ft-lbs for WPL6 material (see Tables 5 and 6).
Materials used for low temperature service have deliberate alloy additions and/or heat treatments to enhance fracture toughness at low service temperatures. In addition, fine grained melting practice improves low temperature service.

Do these low temperature materials also have a upper temperature limit?
