The steel shall be fully killed and fine-grain. ASTM A350 covers several grades and classes:Grade LF1, Grade LF2, Grade LF3, Grade LF5, Grade LF6, Grade LF9, Grade LF787; and Class 1, Class 2, Class 3. All the forgings supplied by Metals-Piping will be ultrasonically tested.
ASTM A350 LF2 Flanges LTCS SA350 GR LF2 CL1 / CL2 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
ASTM A350 LF2 grade have two class,class1 and class2,these two classes materials have same mechanical and chemical data,but the impact test request is different.A350 LF2 class1 test temperature is -46,while class2 is in -18,the two classes also have different average energy and minimum energy requirements. ASTM A350 LF2 steel material
ASTM A350 Lf2 Flanges, Sa350 Gr Lf2 Forged Flange, Lf2 Cl1 As specified by the cs astm a350 gr lf2, after hot working and before reheating the alloy meant for heat treatment, the forging shall be allowed to cool substantially below its transformation range. Forgings of grades like the astm a350 lf2 class 1 and class 2 apart from Grade LF787 must be furnished in a normalized condition.

Sep 30, 2019 · ASTM A350/ ASME SA-350 LF2 is a steel grade mainly applied to low temperature service. However, according to ASME B31.3 and ASME Boiler and Pressure Vessel Codes, it can also be used for high temperature applications. A very common use is that they can be used for the manufacture of tubesheets for heat exchangers and heaters in high temperature and high pressure service.
LF2 LCB LCC Carbon Steel Valve Material Low Temperature Global Supply Line stocks and indents a large range of carbon steel valves in low temperature carbon steel such as forged ASTM A350 LF2 and its cast equivalent ASTM A352 LCB. Higher grades such as ASTM A352 LCC and Alloy (Nickel) based forged carbon steel A350-LF3 and its cast equivalent A352-LC3 are also available on an indent basis.

Jun 06, 2006 · SA-350 Grade LF2 Class 1 is required to have 15 ft-lbs impact energy at -50 deg F, (LF2 Class 2 is required to have 20 ft-lbs at only 0 deg F) Grade LF6 Classes 1 and 2 are required to have 20 ft-lbs at -60 deg F. You also need to evaluate the strength requirements (there are differences). I suggest you review this specification carefully.Allowable Stresses for ASTM A350 LF2 - Piping & PipelineSep 30, 2019 · Both Class 1 and Class 2 of ASTM A350 LF2 forgings can be used for piping applications of ASME B31.3. The piping applications include common process piping and high pressure piping of of Chapter IX. The basic allowable stresses in tension and allowable stresses in tension for ASTM A350 LF2 are listed in the Table A-1 and Table K-1, respectively.
