Hastelloy B-3 Coiled Tubing (UNS N10675 / W.Nr. 2.4600)
High-strength corrosion-resistant alloy Pipe Tube for chemical and petrochemical processing
As a leading supplier of high-performance Hastelloy tubing, SEATHER TECHNOLOGY specializes in the manufacture of high-quality and customized Hastelloy® B-3® (UNS N10675) coiled tubing for demanding corrosion-resistant applications.
Hastelloy B-3 is a nickel-molybdenum alloy offering exceptional resistance to pure hydrochloric, hydrobromic, and sulfuric acids. Compared with earlier B-series alloys, it features greatly improved metallurgical stability, which minimizes sensitivity during welding, fabrication, and long-term service.
Hastelloy B-3 coiled tubing is a continuous, small-diameter tube produced by precision forming, welding, continuous cold drawing, and coiling of Hastelloy B-3 strip. To ensure a clean and oxide-free internal surface throughout the full tube length, SEATHER applies a bright annealing process, effectively preventing oxide scale formation inside the tubing.
SEATHER Hastelloy B-3 coiled tubes provide excellent corrosion resistance, good high-temperature performance, and superior continuity, making them ideal for applications requiring long, uninterrupted tube lengths and reliable system integration. Both welded Hastelloy B-3 coiled tubing and seamless Hastelloy B-3 coiled tubing are available to suit different service conditions and technical requirements.
Please note that, due to differences in manufacturing processes, the maximum available length of seamless Hastelloy B-3 coiled tubing is shorter than that of welded Hastelloy B-3 coiled tubing of the same size. Our technical team will be pleased to confirm achievable lengths and recommend the most suitable option for your application.
With advanced production technology and strict quality control, SEATHER TECHNOLOGY delivers reliable Hastelloy B-3 coiled tubing solutions for highly corrosive and high-performance environments.

ρ = Density, π = 3.1415926…
What is Hastelloy B-3 (UNS N10675)
Alloy B-3 also referred to as the UNS N10675/W.Nr. 2.4600 alloy.
Alloy B-3 is similar to alloy B-2 in terms of resistance to non oxidizing agents, resistance to stress corrosion & pittings, non formation of grain boundry.
Like other nickel alloys (in the mill annealed condition), it is ductile, can be formed and welded, and resists stress corrosion cracking in chloride-bearing solutions.
Also, it is able to withstand fluoride-bearing media and concentrated sulfuric acid, both of which result in damage to zirconium alloys.
Alloy B-3 is widely used in numerous chemical process industry, especially in the construction of reaction vessels for pure, reducing acid service.
B-3 alloy is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and coated electrodes.
