Description

ASTM A350 LF2 Flange for Low Temperature carbon Steel

A350 LF2 flanges are manufactured in accordance with ASTM A350 standard which specifies low-temperature carbon steel forgings for piping components such as flanges, fittings, valves and other similar parts. A350 LF2 flanges are commonly used in cryogenic applications where low temperature materials are required to ensure efficient and reliable operations.

ASTM A350 (ASME SA350) is the standard specification for carbon steel and low alloy steel forged flanges and flanged fittings for low temperature services. ASTM A350 LF2 Class 1 is commonly used grade with yield strength minimum 240 Mpa, and tensile strength in 480 Mpa to 655 Mpa, impact test temperature at -45℃.
