The ASTM A350 Class 2 Forged Steel Fittings have higher mechanical properties than the class 1 fittings but the class 1 are the most used in applications. There are wrought austenitic carbon steel SA350 Gr Lf2 Forged Fittings that are used in applications like the petrochemical, petroleum, oil and gas and other fluid transmission pipe lines.
ASTM A350 LF2 Gate Valve with Integral Flange, 600 LB, 3/4 Inch Baltic
The A350 LF2 Class 1 Flange is the most used with class 2 being used in specific applications. The flanges can also be heat treated for hardening. The heat treatment methods are normalizing and tempering. The A350 LF2 Blind Flange is a type of flange that is fitted on to the ends of pipes to close a pipe line completely. These could be bolted for easy removal at maintenance or be welded.
