ASTM A350 LF2 Flanges is 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 that require cold temperature service where corrosion resistance is not important. A105 allows that for each .01% Carbon below .35, an increase of .06% Manganese is permitted over 1.05 to a maximum of 1.35. This explains the typical analysis above.
A105 and A350-LF2 are standard designations for forged carbon steel piping components. A105 for ambient and higher-temperature accommodation; A350-LF2 for low-temperature accommodation with Charpy V-Notch impact energy testing. Components include flanges, sundry fittings, and valves.
Some components may be machined from a sultry rolled or forged bar, congruously heat-treated, up to and including NPS 4. Visually perceive details in the ASTM designations
Customarily, the material ASTM A350 LF2 Flanges is a general Carbon steel grade that is supplied either in a Normalised, Normalised, and Tempered condition or a Quenched and Tempered condition. The ASTM A350 LF2 Flanges is typified by having both moderate vigor and impact toughness. Ergo the ASTM A350 LF2 Flanges is utilized extensively in the manufacture of flanges and fittings. The ASTM A350 LF2 Flanges is withal utilized in applications where corrosion resistance is not paramount, namely in arctic temperature accommodation.
