ASTM A350 LF2 Flange Physical Properties

Physical properties of A350 LF2 steel in the annealed condition

A350 LF2 Flange Welding

ASTM A350 LF2 is readily weldable by any technique

A350 LF2 Flange Heat Treatment

Normalising – Heat to 860 - 920°C for a time commensurate with ruling section, Air cool (If Required)
Hardening – Heat to 89 – 960oC for a time commensurate with ruling section and quench in Water.
Tempering – Re-heat to 59oC Minimum as required, dependent on final required properties. Hold for a time commensurate with the ruling section and cool in still in air.

A1350 LF2 Flange Forging

Forging Temperature for this material should be 90 – 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

A350 LF2 Flange Machining

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.

Frequently asked questions

What is ASTM A350 LF2?

ASTM A350 LF2 is a low-temperature carbon steel forging grade requiring Charpy impact testing for cold-service piping flanges and fittings.

A350 LF2 vs A105?

A105 is for ambient/elevated temperature. A350 LF2 is specified when low-temperature toughness is required.

What pipe grade pairs with LF2 flanges?

Commonly ASTM A333 Grade 6 (and related LTCS pipe). Confirm the project piping class.

What belongs on the purchase order?

A350 LF2 (class if required), impact test temperature, flange type/facing, size/class, bore/schedule, and MTC.
