Products Description
N10665 Nickel Alloy Steel Tube is a nickel-based alloy steel pipe widely used in the oil and gas industry to manufacture pipelines, valves, pump bodies, and other equipment.
Advantages
Hydrochloric Acid Corrosion Resistance
N10665 pipe contains 26-30% Mo, with Ni as the primary component. Smelted in a vacuum induction furnace to ensure purity, it offers enhanced corrosion resistance to non-oxidizing acids such as hydrochloric acid and hydrogen chloride, making it suitable for highly corrosive fluid systems in chemical plants.
High Tensile Strength
Tensile strength is no less than 760 MPa. Low carbon content (≤ 0.02%) and solution heat treatment optimize the grain structure, while cold working with high-precision drawing equipment enhances overall mechanical properties. It is suitable for high-pressure, high-temperature, and continuous load conditions.
Excellent Ductility
Elongation reaches 40%. Hot extrusion and medium-temperature annealing create a uniform austenitic structure, minimizing cold work hardening. This makes it suitable for secondary processing such as on-site bending and welding, reducing the risk of rework due to brittle cracking.
Wide Dimensional Compatibility
Outer diameters range from 19–610mm, and wall thicknesses from 2–60mm. Utilizing a multi-die rolling process and automatic straightening control system, the product supports a wide range of structural dimensions, enabling flexible configuration in various fluid transport or heat exchange systems.

FAQ
Q: What is N10665 Nickel Alloy Steel Tube?
A: Common Trade Names: Hastelloy B2, Alloy B2; Nimofer 6928. Alloy B2 (UNS N10665 / W.Nr. 2.4617) is a solid solution strengthened, nickel-molybdenum alloy, typically used in extreme reducing conditions.
Q: What are the primary uses of N10665 Nickel Alloy Steel Tube?
A: Applications. Alloy B-2 is used mostly in chemical processing for equipment handling hydrochloric acid (all concentrations and temperatures), sulfuric acid, acetic acid, and phosphoric acid. It is also used in high-temperature applications when a low coefficient of thermal expansion is required.
Q: How does N10665 Nickel Alloy Steel Tube compare to other alloy steels?
A: Alloy B-2 (UNS N10665) is an advanced version of Alloy B. It has superior corrosion resistance in weld-heat-affected zones compared to Alloy B, due to reduced carbon and silicon contents and a restricted range of iron content.
Q: What industries commonly use N10665 Nickel Alloy Steel Tube?
A: Hastelloy B-2® (UNS N10665) is a nickel-base wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. Common applications include chemical processing, vacuum furnaces, and mechanical components in reducing environments.
