Carbon steel forged pipe fittings are made from forged carbon steel material. Forging is a process that creates very strong fittings. Carbon steel is heated to molten temperatures and placed in the dies. The heated steel is then machined into the forged steel fittings.
Common carbon steel material standard include ASTM A105,ASTM A182,ASTM A350 LF2,ASTM A694 etc. Forged fittings standard including ASME B16.11, MSS-SP-79, MSS SP-83, MSS SP-95, MSS SP-97, and BS 3799 standards. They are used to build connection, between nominal bore schedule pipe and pipelines. They are supplied for extensive application range. Carbon steel forged pipe fittings, usually refer to two types of fittings: socket weld and threaded fittings. Pressure rating: Class 2000,3000 ,6000 and 9000 series.
Threaded Fittings
Threaded fittings is a common used type of forged fittings in material of carbon steel. The threads can be NPT, BSPP, BSPT, PF, PT, MPT.

Carbon Steel Material properties
Carbon steel is often divided into two main categories: low-carbon steel and high-carbon steel. It may also contain other elements, such as manganese, phosphorus, sulfur, and silicon, which can affect its properties. Carbon steel can be easily machined and welded, making it versatile for various applications. It can also be heat treated to improve its strength, hardness, and durability.
We can supply carbon steel forged pipe fittings of different materials, such as ASTM A105, A350 LF2, A182 F5, F9, F11, F12, F22, F91,A694 F42,F46,F52,F60,F65 etc.

Advantage Forged Fittings
Corrosion resistant
Highly durable
Lightweight
Low maintenance
Long service life
Forged fittings are basically used for piping and tubing systems to connect and change direction of the flow that conveys liquid, gas, and occasionally solid materials.When selecting and using forged fittings, attention should be paid to their quality and performance to ensure the safety, stability, and efficiency of fluid transportation, providing reliable guarantees for fluid transportation systems in various industries.
