What is ASTM A350 LF2 flange?

The ASTM A350 LF2 forged flange means the flange which material is ASTM A350 LF2.ASTM A350 LF2 has good machinability,dependent on condition,and operations such as sawing,turning,broaching,milling etc.It can be accomplished satisfactorily using standard machine tool manufacturers recommended speeds and feeds.

ASTM A350 LF2 flange is usually used for ship building,oil and gas transport in the cold weather on -50℃ to 800℃.Commonly people think it’s better than the ASTM A105 steel grade material.

ASTM A350 LF2 flange

ASTM A350 Grade LF2 is a general carbon steel usually supplied in the Normalised,Normalised 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.
