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.
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.
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.

Q1: What is Alloy B-2 (UNS N10665)?
A: Alloy B-2 is a nickel-molybdenum alloy known for superior resistance to reducing environments, especially hydrochloric acid.
Q2: What industries commonly use Alloy B-2 pipes and tubes?
A: They are widely used in chemical, petrochemical, pharmaceutical, and pollution control industries.
Q3: Can Alloy B-2 be welded easily?
A: Yes, it has good weldability, but care must be taken to avoid heat-affected zone corrosion. Proper post-weld cleaning is recommended.
Q4: What standards apply to Alloy B-2 pipes and tubes?
A: The common standards are ASTM B619, ASTM B622, and ASTM B626.
Q5: Why choose Alloy B-2 over stainless steel?
A: While stainless steels may fail in aggressive hydrochloric acid environments, Alloy B-2 maintains resistance, reducing downtime and repair costs.
