ASTM A105 A350 LF2 / LF3 Carbon Steel Pipe Fittings Forged Steel Fittings
Carbon steel pipe fittings can be divided into forged steel fittings and butt weld fittings. ASTM A105 and A350 LF2 / LF3 are common grades of carbon steel material, and commonly used to manufacture forge steel flange and fittings of small diameter piping. This carbon steel material grade is used for ambient- and higher-temperature service in pressure systems.
