Higher grades such as ASTM A352 LCC and Alloy (Nickel) based forged carbon steel A350-LF3 and it's cast equivalent A352-LC3 are also available on an indent basis. LF2 and LCB low temperature carbon steels are suitable for continuous service down to -46ºC, up to 345ºC.

ASTM A350 LF2 – Carbon Steel

ASTM A350 Grade LF2 is a general Carbon steel usually supplied in the Normalised, Normalised and Tempered or Quench and Tempered condition.
It is typified by having moderate strength and impact toughness and is used extensively for the manufacture of flanges and fittings, and applications which require cold temperature service where corrosion resistance is not important.

Forging

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.

Heat Treatment

Normalising – Heat to 860 - 920°C for a time commensurate with ruling section, Air cool (If Required)
Hardening – Heat to 890 – 960°C for a time commensurate with ruling section and quench in Water.
Tempering – Re-heat to 590°C Minimum as required, dependent on final required properties. Hold for a time commensurate with the ruling section and cool in still in air.

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.

Welding

ASTM A350 LF2 is readily weldable by any technique.

Carbon steel Grade LF2 is impact tested at -50°F. Three and one half nickel Grade LF3 material is impact tested for services down to -150°F.

Charpy V-Notch Impact Testing is required.

Refer to Specifications A/SA961 for additional requirements. Optional supplementary requirements are listed in A/SA350 and A/SA961.

Scope: The specification listed above reflects the common materials required for manufacture and fabrication of items for use in Low Temperature Service.

A350 FITTING / FLANGE SPECIFICATIONS

American Piping Products stocks A/SA350 forged seamless components for low-temperature pressure systems in the following grades:

  • A/SA350-LF2 CL1 / CL2
  • A/SA350-LF3 CL1

Scope

ASTM A350 (also known as ASME SA350) covers several grades of carbon and low-alloy steel forged or ring-rolled flanges, forged fittings and valves intended primarily for low-temperature service and requiring notch toughness testing. They are made to specified dimensions, or to dimensional standards, such as the ASME and API specifications.  Product furnished to this specification shall conform to the requirements of specification A961/A961M.

Process

The steel shall be produced by any of the following primary processes: Open-hearth, basic-oxygen, electric-furnace or vacuum-induction melting (VIM). The steel shall be fully killed, fine-grain practice. The molten steel may be vacuum treated prior to or during pouring of the ingot. Material for forgings shall consist of ingots or forged, rolled, or strandcast blooms, billets, slabs or bars.

Heat treatment

After hot working and before reheating for heat treatment, the forging shall be allowed to cool substantially below the transformation range. Forgings of grades other than Grade LF787 shall be furnished in the normalized, or in the normalized and tempered, or in the quenched and tempered condition.
