ASTM A350 LF2 Low Temperature Flange
GNEE is a well-known supplier, manufacturer and exporter of ASTM A350 LF2 Flange, which is made of low temperature carbon steel and complies with ASTM A350 specifications to work at low temperatures.
A350 LF2 forged flanges are divided into Class 1 flanges and Class 2 flanges. The notch toughness requirements of Class 1 A350 LF2 are lower than Class 2 A 350 lf2. CL 1 requires simple beam V-notch impact testing at a minimum temperature of -46 °C, while Level 2 is -101 °C.
The "LF" in A350 LF2 stands for "low temperature," indicating that these flanges are suitable for use in environments where temperatures may drop below freezing. A350 carbon steel LF2 cryogenic flange exhibits excellent toughness and impact resistance even at low temperatures, making it suitable for applications requiring cryogenic systems and refrigeration such as oil and gas, chemical processing, power generation and cryogenic engineering.
