ASTM A350 Lf2 Flanges

India-based manufacturer of ASTM A350 Lf2 Flanges, meeting ANSI / ASME B16.5, B16.48, B16.47, BS 10, BS 4504, and EN-1092-1 specifications

Astm A350 LF2 flanges can be used at temperatures as low as -20 °F (LF1), -50 °F (LF2), and -150 °F (LF3).

Up to 1.65% manganese and up to 1% carbon are present in carbon steel A350 LF2 flanges, while other elements are present in amounts too tiny to have an impact on the material’s characteristics.

900–1200 °C is the forging temperature for SA350 LF2 flanges. Soak periods ought to be minimised to prevent severe scaling. However, the core needs to have adequate time to reach furnace temperature. It should be let to cool in steady air after forging.

Flange WN A350 LF2 is widely used in the production of flanges and fittings, as well as in applications that call for cold temperature service and do not require corrosion resistance because to its mild strength and impact toughness.

Any method can be easily used to weld blind flange lf2. This flange is devoid of both a hub and a bored centre. Its face thickness is comparable to that of a flange, and its bolting pattern and face type match.

The standard specification for forged flanges and flanged fittings made of carbon steel and low alloy steel for low temperature applications is flange material A350 lf2.

A350 LF2 pipe flange is a type of carbon steel that is often provided in one of three conditions: normalised, normalised and tempered, or quench and tempered.

Pipelines and forged flanges are the main applications for the A350 LF2 Class 1 flange.

Depending on the condition, the a350 lf2 welding neck flange has extremely good machinability. Standard machine tool makers with required feeds and speeds can be used to expertly and satisfactorily perform operations like turning, sawing, milling, broaching, etc. It is made up of a circular fitting that has an elongating rim surrounding the edge. It is usually butt welded to a pipe after being machined from forging. A number of drilled holes in the rim enable the flange to be fastened to another flange using bolts.
