Grades of ASTM A350 Carbon Steel Flanges

ASTM A350 LF1 Flange

The ASTM A350 Grade LF1 Flange is a material specification for carbon and low alloy steel forgings that calls for notch toughness testing on piping components. Forged flanges, fittings, valves, and other forged and machined parts are included. Chemical structure, mechanical properties, and impact tests for notch durability are all covered in this specification.

ASTM A350 LF2 Flange

The ASTM A350 LF2 is a forged carbon/low-alloy steel grade of forged flanges, forged fittings, and forged valves that are intended for low-temperature operation and must pass notch durability inspection. The LF2 steels are divided into two classes: Class 1 and Class 2.

ASTM A350 LF3 Flange

Flanges made to ASTM A350 LF3 requirements can withstand temperatures as low as 150 degrees Fahrenheit (LF3.) These ASTM A350 LF3 Flanges are primarily used in high-energy/high-temperature channeling applications. All ASTM A350 LF3 Flanges are available with either a raised face or a flat face. At ambient temperature, the working pressure for a B16.5 ASTM A350 LF3 Flange is approximately 2.4 times the Flange Class.
