Hastelloy B-3 Welded Pipe Tube (UNS N10675 / W.Nr. 2.4600)
High-strength corrosion-resistant alloy Pipe Tube for chemical and petrochemical processing
As a leading Chinese manufacturer and supplier of Hastelloy pipes and tubes, SEATHER TECHNOLOGY specializes in the production of Hastelloy® B-3® (UNS N10675) welded pipes and tubes in a wide range of sizes and specifications to meet demanding industrial applications.
Hastelloy B-3 is a high-performance nickel-molybdenum alloy renowned for its exceptional resistance to pure hydrochloric, hydrobromic, and sulfuric acids. Compared with earlier B-series alloys, Hastelloy B-3 offers significantly improved metallurgical stability, which greatly reduces sensitivity to fabrication variables and minimizes concerns during welding, forming, and long-term service.
SEATHER Hastelloy B-3 welded pipes and tubes are manufactured by precision forming and welding of high-quality Hastelloy B-3 strip or plate. As the performance of welded products is highly dependent on raw material quality, SEATHER exclusively sources materials from reputable large-scale mills. Combined with our advanced slitting, forming, and welding technologies, this ensures excellent weld integrity, dimensional accuracy, and consistent mechanical and corrosion-resistance properties.
For applications requiring enhanced corrosion resistance and structural uniformity, solution annealed Hastelloy B-3 welded pipes and tubes are also available. SEATHER is equipped with in-line solution annealing facilities, enabling us to deliver products that meet higher technical and service requirements.
With strict quality control and mature manufacturing expertise, SEATHER TECHNOLOGY provides reliable Hastelloy B-3 welded pipe and tube solutions for chemical processing, petrochemical, and other highly corrosive 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.
