Hastelloy B-3 Foil (UNS N10675 / W.Nr. 2.4600)
High-strength corrosion-resistant alloy Foils for chemical and petrochemical processing
As a professional nickel alloy foil supplier, SEATHER TECHNOLOGY manufactures high-quality Hastelloy B-3 foil (UNS N10675) tailored to meet your precise application requirements.
HASTELLOY® alloy B-3 (UNS N10675) is a high-performance nickel-molybdenum alloy designed for exceptional resistance to reducing environments, including hydrochloric acid at all concentrations and temperatures. As a solid-solution-strengthened alloy, Hastelloy B-3 combines excellent corrosion resistance with very high mechanical strength, improved thermal stability, and enhanced resistance to intergranular corrosion compared with earlier B-series alloys.
All Hastelloy B-3 foil (UNS N10675) foils produced by SEATHER comply strictly with ASTM B333, ensuring stable chemical composition, mechanical integrity, and consistent performance. Through precision cold rolling, we achieve accurate dimensions, uniform thickness, and excellent mechanical strength. Controlled heat-treatment processes allow us to optimize tensile strength, hardness, and structure to meet demanding engineering standards.
SEATHER TECHNOLOGY supports full customization based on your project needs. Whether you require specific mechanical properties, hardness ranges, ultra-tight dimensional tolerances, or special surface finishes, our technical team provides professional evaluation and tailored solutions.

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.
