Alloy C276 is considered among the list of Superalloy products. Superalloys (or super metals)
like Alloy C276 Pipe and Alloy C276 Tube are used in severe environments for their capability
to handle corrosive situations.
Hastelloy C-276 Seamless Pipe : ASTM/ASME B 622 / SB 622
Hastelloy C-276 Seamless tube : ASTM/ASME B 444 / SB 444
Hastelloy C-276 ERW Pipe : ASTM/ASME B 619 / SB 619
Hastelloy C-276 ERW Tube : ASTM/ASME B 626 / SB 626
Hastelloy C-276 is a nickel-molybdenum alloy with elements of chromium. Hastelloy C276 pipe,
hastelloy C276 seamless tube, and hastelloy C276 seamless pipe material has excellent
corrosion resistant properties and is known for its extensive use with chemical and waste
Hastelloy C-276 or UNS N10276 are manufactured using processes such as ERW (Electric
Resistance Welded), Seamless and EFW (Electric Fusion Welding) by hastelloy C276 pipe
manufacturers. C276 Hastelloy Pipe and Tubes have different forms such as round, square,
rectangle etc. having specific end as Plain End, Bevel End and Threaded End with nominal
thickness of different schedule ranging from SCH 5 to SCH XXS.
The process through which pipes and tubes can be manufactured include cold pilgering process,
Extrusion process, tube mill Process also Piercing process followed by heat treatment and
Fabrication and Heat Treatment
Due to the hastelloy C276 pipe specification, it hardens more readily than most austenitic
stainless steels, and may require several stages of cold work, with intermediate anneals.
INCONEL alloy C-276 is normally annealed at 2100-2150°F (1150-1175°C) and rapidly cooled
such as by water quenching. This process is practiced by various hastelloy C276 pipe suppliers
and hastelloy C276 tube suppliers.
Hastelloy C-276 alloy can be forged, hot-upset and impact extruded. All of the common
methods of welding can be used, although the oxyacetylene and submerged arc processes are
not recommended when the fabricated item is for use in corrosion service.
Hastelloy C276 pipe high temp mechanical properties include good creep and oxidation
resistance and Hastelloy C 276 Tubes are also known as high performance alloys, which can be
formed in different shapes.

In addition to its corrosion resistance, Hastelloy C 276 Seamless Pipes have high strength, good
metallurgical stability and favorable fabrication characteristics. There are various hastelloy
C276 pipe sizes and hastelloy C276 tube sizes you can shop for from manufacturers.

Hastelloy C-276 is a good choice of alloy if versatility and high resistance to reducing and
oxidizing acids is required. They are highly resistant to stress-corrosion cracking and pitting
corrosion. However, hastelloy C276 tube cost and hastelloy C276 pipe cost varies depending
on the manufacturer or supplier you purchase it from.
Hastelloy also has excellent resistance to phosphoric acid containing solution and has excellent
resistance to corrosion by seawater especially under crevice conditions. Hastelloy C 276 pipes
and tubes are used in fasteners, forging, sulfuric acid reactors, components used for sour gas,
beach plant and digester for manufacturing of paper and pulp etc. due to the hastelloy C276
tube price and hastelloy C276 pipe price; it is used in various corrosive environments. The
hastelloy C276 seamless pipe price is also relatively lower than other alloys hence it is
favorable for many industries.
