ASTM B366 WPHB-3 UNS N10675 Butt Weld Pipe Fittings - Premier Global Manufacturer, Largest Stockist, Top Supplier & Worldwide Exporter

ASTM B366 WPHB-3: High-Performance UNS N10675 Butt Weld Pipe Fittings

DIPTI METAL INDUSTRIES is a distinguished global ASTM B366 WPHB-3 manufacturer, largest UNS N10675 stockist, and worldwide UNS N10675 exporter of ASTM B366 WPHB-3 Butt Weld Pipe Fittings. The "WP" in WPHB-3 stands for "Wrought Pipe," indicating fittings produced from wrought materials, ensuring superior structural integrity and reliability. "HB-3" designates the material as UNS N10675 (commonly known as Hastelloy B-3 or Alloy B-3 / CR HB3 / W. Nr. 2.4600), an advanced nickel-molybdenum alloy.

UNS N10675 (Hastelloy B-3 / Alloy B-3 / W. Nr. 2.4600)

UNS N10675, or Hastelloy B-3, is a sophisticated nickel-molybdenum alloy engineered for outstanding resistance to strong reducing chemical environments, particularly hydrochloric acid at all concentrations and temperatures. It represents a significant advancement over earlier B-series alloys by possessing exceptional thermal stability. This key feature minimizes the formation of deleterious intermetallic phases in the weld heat-affected zone, allowing for robust welded fabrications without requiring a post-weld solution heat treatment in many cases. Its high molybdenum content (typically 28.5%) and very low chromium content (max 1.5%) are critical for its performance. Key properties include:

• Exceptional Hydrochloric Acid Resistance: Offers superb resistance to HCl in various concentrations and temperatures, a hallmark of the Hastelloy B family.
• Superior Resistance to Strong Reducing Environments: Highly effective in other non-oxidizing acids like concentrated sulfuric acid, phosphoric acid, and acetic acid.
• Greatly Enhanced Thermal Stability: Unique composition resists the formation of deleterious phases in the weld heat-affected zone, ensuring consistent corrosion resistance after welding. This is a critical improvement over previous B-series alloys.
• Excellent Resistance to Localized Corrosion: Superior performance against pitting, crevice corrosion, and stress-corrosion cracking in relevant reducing chemical media.
• Good Weldability & Formability: Can be readily fabricated using standard nickel-alloy welding and forming practices, with its improved thermal stability offering greater flexibility in manufacturing complex components.

Our ASTM B366 WPHB-3 fittings ensure robust and reliable connections, maintaining system integrity in critical process piping where strong resistance to hydrochloric acid and other aggressive reducing chemicals, combined with superior thermal stability and excellent weldability, is paramount.
