ASTM A350 LF2 Flanges is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
ASTM A350 LF2 Flanges (Standard Specification for Carbon and Low-Alloy Steel Forgings, Requiring Notch Toughness Testing for Piping Components.
ASTM A350 LF2 Specification covrs Several grade of carbon and low alloy steel forged or ring-rolled flanges, forged fittings and valves for low-temperature service. Impact tests shall also be performed and the steel materials shall conform to the required values of minimum impact energy, temperature, and minimum equivalent absorbed energy.

Physical properties of A350 LF2 steel in the annealed condition
ASTM A350 LF2 is readily weldable by any technique
Normalising – Heat to 860 - 920°C for a time commensurate with ruling section, Air cool (If Required)
Hardening – Heat to 890 – 960oC for a time commensurate with ruling section and quench in Water.
Tempering – Re-heat to 590oC Minimum as required, dependent on final required properties. Hold for a time commensurate with the ruling section and cool in still in air.
Forging Temperature for this material should be 900 – 1200oC. Soak times should be kept to a minimum to avoid heavy scaling, but sufficient time should be given to allow centre to achieve furnace temperature. After forging pieces should be allowed to cool in still air
ASTM A350 LF2 has good to very good machinability, dependent on condition, and operations such as sawing, turning, broaching, milling etc can be accomplished satisfactorily using standard machine tool manufacturers recommended speeds and feeds.
