Product Description

ASTM B622 C22 Heat Exchanger Tube Chemical Composition

UNS Designation Ni Cr Mo Fe W C Si Co Mn V P S
N06022 50.0min 20.0-22.5 12.5-14.5 2.0-6.0 2.5-3.5 0.15max 0.08 2.5max 0.50max 0.35max 0.02 0.02

 

ASTM B622 C22 Heat Exchanger Tube Corrosion Resistance & Performance

Key Strengths:

Resists pitting, crevice corrosion, and stress corrosion cracking.

Superior to C276/C4 alloys in mixed-acid environments (e.g., HCl + HNO₃) 

Critical Environments:

Wet chlorine, nitric acid, seawater, chlorides (FeCl₃, CuCl₂).

Reducing media (e.g., sulfuric/acetic acid) and oxidizing agents 

Welding Performance:

Resists intergranular precipitation in heat-affected zones.

No post-weld heat treatment needed for most applications

 

ASTM B622 C22 Heat Exchanger Tube Applications

Chemical Processing: Reactors, heat exchangers handling chlorides/acetic acid 

Oil & Gas: Downhole components in sour gas (H₂S) environments 

Pollution Control: Flue gas desulfurization (FGD) systems, scrubbers 

Pharmaceuticals: High-purity equipment requiring sterile corrosion resistance 

Specialized Uses: Geothermal wells, nuclear fuel reprocessing, pesticide production 

 

ASTM B622 C22 Heat Exchanger Tube Certifications & Equivalents

International Standards:

DIN 2.4602, EN NiCr21Mo14W, JIS NW6022.

Related Product Forms:

Welded Pipes: ASTM B619.

Fittings: ASTM B366 (ASME B16.9).

 

ASTM B622 C22 Heat Exchanger Tube Limitations & Fabrication Notes

Cost: High due to nickel/molybdenum content (3–5× stainless steel).

Fabrication Challenges:

Requires controlled welding (TIG/laser) to avoid carbide precipitation.

Machining necessitates low speeds and high coolant flow.

Thermal Sensitivity: Prolonged exposure above 650°C may cause embrittlement.

 

ASTM B622 C22 Heat Exchanger Tube Conclusion

ASTM B622 C22 SMLS tubes offer unmatched corrosion resistance in extreme industrial environments, validated by global standards and versatile performance across chemical, energy, and pharmaceutical sectors. Their balanced Ni-Cr-Mo-W composition ensures longevity in aggressive media, though cost and fabrication complexity require careful project planning. For dimensional tables or project-specific specs, manufacturers like SteelJRV or Epower Metals provide detailed datasheets.
