Threaded Industrial Pipe Fittings Class 3000 Forged ASTM A105 ASME B16.11
Forged steel fittings have two types that socket weld fittings and threaded fittings, which avialble in Class 2000, 3000, 6000 and 9000. ASTM A105 is represitive grade 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.
