In ASTM A350 standard ,there are 7 different steel grades,LF1,LF2,LF3,LF5,LF6,LF9,LF787.ASTM A350 LF2 forged steel flange is the most widely used material in the low temperature pipeline system.
ASTM A350 Grade LF2 is a general carbon steel usually supplied in the Normalized, Normalized and Tempered or Quench and Tempered condition .It is typified by having moderate strength and impact toughness and is used extensively for the manufacture of flanges and fittings, and applications which require cold temperature service where corrosion resistance is not important.
Carbon steel Grade LF2 is impact tested at -50°F. Three and one half nickel Grade LF3 material is impact tested for services down to -150°F.
