Check ASTM A350 LF2 Equivalent Material And A350 Gr. LF2 CL.1 Blind Flange Specification.


Generally, this carbon steel or alloy steel ASTM A350 LF2 Flanges are forged in order to improve the mechanical properties, impact resistance and fatigue resistance. The specification mentions three different melting procedure in order to produce these flanges i.e open hearth, electric furnace, basic oxygen, or vacuum-induction melting. In addition to being forged, the materials used to produce the A350 LF2 Welding Neck Flange are to be heat treated along with a heat and product analysis conducted on them. The heat treatment used by manufacturers on the Carbon Steel A350 Lf2 Flanges includes normalizing, tempering, quenching as well as precipitation heat treatment. Grade LF2 under specification ASTM A350, is segregated further into Class 1 and Class 2. Both classes 1 and 2 of the SA350 LF2 WN Flange have the same chemical composition, mechanical properties and allowable stresses.

What Is ASTM A350 LF2 Flanges?


The main characteristic that distinguishes A350 Gr. LF2 CL.1 Blind Flange from Class 2 is its minimum applicable temperature. The minimum applicable temperatures are -50°F for LF2 Class 1 flanges and -0°F for LF2 Class 2 flanges, respectively. The minimum applicable temperature for the A350 LF2 Carbon Steel Blind Flanges is also the standard temperature for a Charpy V-notch impact test.
