Inconel 625 , Nickel Alloy Seamless U Tube ASTM B444 UNS NO8825 For Heat Exchanger
ASTM B444 specifies the requirements for nickel-alloy seamless pipes and tubes, with UNS N08825 (commonly known as Incoloy 825) being a high-performance material designed for aggressive environments. This alloy combines excellent corrosion resistance with mechanical strength, making it suitable for demanding industrial applications.
Inconel 625 Seamless U Tube Composition:
Nickel (Ni): 38-46% (provides corrosion resistance).
Chromium (Cr): 19.5-23.5% (enhances oxidation resistance).
Iron (Fe): Remainder (base metal).
Molybdenum (Mo): 2.5-3.5% (resists pitting/crevice corrosion).
Copper (Cu): 1.5-3.0% (improves resistance to sulfuric acid).
Titanium (Ti): 0.6-1.2% (stabilizes against sensitization during welding).
Carbon (C): ≤0.05% (minimizes carbide precipitation).
Other elements (Mn, Si, S) are controlled to low levels for optimal performance.
Inconel 625 Seamless U Tube Manufacturing:
Produced via extrusion or rotary piercing, seamless tubes ensure superior pressure integrity and uniformity, ideal for high-stress applications. The process avoids weld seams, enhancing reliability in corrosive or high-pressure environments.
Inconel 625 Seamless U Tube Key Properties:
Tensile Strength: ≥586 MPa.
Yield Strength: ≥241 MPa.
Elongation: ≥30% (ensures ductility).
Heat Treatment: Solution annealed at 925-1025°C followed by rapid cooling to optimize microstructure.
Corrosion Resistance: Excels in both oxidizing (e.g., nitric acid) and reducing (e.g., sulfuric, phosphoric acids) environments. Resists stress-corrosion cracking, chloride-induced pitting, and marine atmospheres.
Inconel 625 Seamless U Tube Applications:
Inconel 625 Seamless U Tube Standards Compliance:
Meets ASTM B444 for chemical, mechanical, and dimensional requirements.
Compatible with ASME SB444 for pressure vessel use.
Non-destructive testing (NDT) and hydrostatic testing ensure quality.
Inconel 625 Seamless U Tube Advantages:
Superior performance in extreme temperatures (up to 540°C).
Seamless construction enhances safety in high-pressure systems.
Versatile in multiphase corrosive environments.
