Hastelloy B-3 Seamless Pipe Tube (UNS N10675 / W.Nr. 2.4600)
High-strength corrosion-resistant alloy Pipe Tube for chemical and petrochemical processing
As an industry-leading supplier of nickel-based superalloys, SEATHER TECHNOLOGY manufactures high-quality Hastelloy B-3 (UNS N10675) seamless pipes and tubes engineered for exceptional corrosion resistance and long-term durability.
HASTELLOY® B-3® alloy (UNS N10675) is a high-performance nickel-molybdenum alloy designed for service in strong reducing environments. It exhibits outstanding resistance to hydrochloric acid, sulfuric acid, and other aggressive media, along with excellent thermal stability and structural integrity. These characteristics make Hastelloy B-3 flanges ideal for use in chemical processing, petrochemical, marine engineering, pharmaceutical, and other corrosive industrial applications.
We manufacture Hastelloy B-3 seamless pipes and tubes in strict accordance with ASTM B622, with dimensional tolerances controlled precisely according to ASTM B829. All tubes undergo complete solution heat treatment to ensure a stable microstructure and optimal corrosion resistance. Each pipe is also subjected to hydrostatic testing to guarantee structural integrity and performance under pressure.
Our default surface condition is pickled, ensuring a clean and corrosion-free finish suitable for most industrial applications. For customers requiring enhanced surface quality, we offer customized polishing options to meet specific project or equipment requirements.
With advanced manufacturing technology, strict quality assurance, and competitive pricing, SEATHER TECHNOLOGY provides reliable Hastelloy B-3 seamless pipe and tube solutions for critical applications in chemical processing, pollution control, marine engineering, and high-temperature 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.
