Alloy Steel A182 F5 Forged Fittings

ASTM A182 F5 Coupling is one of the most common used alloy steel pipe fittings, which has long service life and excellent capability for High-Temperature Service. What is ASTM A182?

No matter it is stainless steel forging or alloy steel forging, there are always ASTM A182 Forged Fittings.

ASTM A182 is a standard specification that covers Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts. It specified the chemical composition, mechanical properties, heat treatment, testing, and other precautions of products.

Besides, this standard just sets the quality standard of forged fittings, but not mention about their dimensions.

Chrome Moly Alloy Steel A182 F5 Forged Fittings

Alloy steel has generalized and narrow sense. In generalized, every steel is an alloy, but the term “alloy steel” is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Alloy Steel F5 is an alloy in narrow sense. It is called chrome moly alloy steel with 4 to 6 % chromium. Its yield strength are up to 40 ksi, which larger than many stainless steels. Because it is a mixture of many alloying elements, it combines various advantages together, you can use it in many conditions even it is corrosive.

Therefore, ASTM A182 F5 Coupling are recommended for high-temperature services, their good chemical composition allows durability at high temperatures. It also resists hydrogen attack and corrosion, oxidation and sulfur corrosion due to their strong Chromium-Molybdenum mixture.

A182 F5 Coupling Manufacturer

Now we get many information about properties of ASTM A182 F5 Coupling, but where can we get their detailed size?

There are three different standard which cover the dimension. They are GB/T 14383, ASME B16.11, and BS3799. As a manufacturer and exporter, most orders of couplings are manufactured as ASME B16.11.

Pipe Coupling Dimension

The diameter range are from NPS 1/8 to NPS 4 and pressure ratings are Class 3000, Class 6000, Class 9000.
