    Alloy B-2, UNS N10665, Nickel Alloy Steel Pipe/Tube

    Alloy B-2 (UNS N10665) is a nickel-molybdenum alloy widely recognized for its outstanding resistance to reducing environments, such as hydrochloric acid, hydrogen chloride gas, sulfuric acid, and phosphoric acid. When manufactured into Nickel Alloy Steel Pipes and Tubes, Alloy B-2 provides excellent mechanical strength, corrosion resistance, and reliability in demanding chemical process applications.


    Product Features

    1.Superior Corrosion Resistance: Excellent performance against hydrochloric acid across the full concentration and temperature range.

    2.High Purity Composition: Low iron and carbon minimize carbide precipitation and maintain corrosion resistance after welding.

    3.Good Fabricability: Alloy B-2 pipes and tubes can be formed and welded using standard methods, making them suitable for complex engineering projects.

    4.Thermal Stability: Maintains strength and toughness even at elevated temperatures.

    5.Versatility: Ideal for heat exchangers, piping systems, pressure vessels, and evaporators in harsh chemical environments.

    Advantages of Alloy B-2 (UNS N10665) Steel Pipe

    1.Long service life due to resistance to uniform and localized corrosion.

    2.Reduced maintenance costs compared to conventional stainless steels.

    3.Reliable performance in industries where process purity and safety are critical.

    4.Adaptable for both seamless and welded pipe/tube production.

    5.Global availability in customized sizes and wall thicknesses.
