Hastelloy B-3 Capillary Tube (UNS N10675 / W.Nr. 2.4600)
High-strength corrosion-resistant alloy Pipe Tube for chemical and petrochemical processing
As a leading Chinese supplier of high-performance nickel alloys, SEATHER TECHNOLOGY specializes in the manufacturing of precision Hastelloy® B-3® (UNS N10675) capillary tubes for demanding corrosion-resistant applications.
Hastelloy B-3 is a nickel-molybdenum alloy known for its exceptional resistance to pure hydrochloric, hydrobromic, and sulfuric acids. Compared with earlier B-series alloys, it offers significantly improved metallurgical stability, resulting in greater reliability during fabrication, welding, and long-term service.
Hastelloy B-3 capillary tubes are small-diameter, thin-wall alloy tubes that require advanced manufacturing expertise and strict process control. SEATHER produces these capillary tubes from high-quality Hastelloy B-3 coil tubing, which is precisely straightened, polished, and finished to achieve excellent surface quality and dimensional accuracy. Due to their precise internal structure and superior corrosion resistance, Hastelloy B-3 capillary tubes are widely used in applications with stringent performance and reliability requirements.
SEATHER can supply both seamless and welded Hastelloy B-3 capillary tubes, depending on size range and application needs. To meet different surface finish and cleanliness requirements, multiple finishing options are available, including MP (Mechanical Polishing), EP (Electropolishing), BA (Bright Annealed), AP (Annealed & Pickled), and other customized treatments.
With strict dimensional tolerances, smooth surfaces, consistent quality, and excellent appearance, SEATHER TECHNOLOGY Hastelloy B-3 capillary tubes provide reliable performance in highly corrosive and precision-critical environments.

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.
