LF2
LF2
General
ASTM A350 LF2 IS A LOW-TEMPERATURE CARBON STEEL FORGING GRADE KNOWN FOR ITS EXCELLENT TOUGHNESS, IMPACT STRENGTH, AND CORROSION RESISTANCE IN BOTH CRYOGENIC AND LOW-TEMPERATURE ENVIRONMENTS. AS PART OF THE ASTM A350 STANDARD, LF2 IS ENGINEERED FOR SERVICE IN CONDITIONS WHERE TEMPERATURES FALL BELOW -50°F (-46°C). THIS MAKES IT AN IDEAL CHOICE FOR INDUSTRIES SUCH AS OIL AND GAS, PETROCHEMICAL, CHEMICAL PROCESSING, AND POWER GENERATION.
Uses
FLANGES, FITTINGS, VALVES, CRYOGENIC STORAGE TANKS, REFRIGERATION APPLICATIONS, LOW-TEMPERATURE ENVIRONMENTS WHERE CORROSION RESISTANCE IS NOT REQUIRED.
