ASTM B366 Alloy C22 (UNS N06022) Butt Weld Elbows | Superior Corrosion Resistant Nickel Alloy Fittings
Introduction: The Pinnacle of Corrosion Resistance in Nickel Alloy Elbows
Alloy C22 (UNS N06022) Butt Weld Elbows manufactured to ASTM B366 represent the gold standard in corrosion resistance for demanding industrial piping systems. This nickel-chromium-molybdenum-tungsten alloy offers exceptional performance in oxidizing and reducing environments, handling chlorides, acids (including sulfuric, hydrochloric, phosphoric), and mixed acid/salt solutions where lesser alloys fail. Our precision elbows ensure leak-free flow direction changes in critical applications worldwide.
Alloy C22 Chemical Composition: Engineered for Maximum Stability
The outstanding corrosion resistance of C22 elbows stems from its tightly controlled, balanced chemistry:
Table 1: ASTM B366 Alloy C22 (UNS N06022) Typical Chemical Composition (Weight % Maximum Unless Noted)
| Element | Nickel (Ni) | Chromium (Cr) | Molybdenum (Mo) | Tungsten (W) | Iron (Fe) | Cobalt (Co) | Carbon (C) | Manganese (Mn) | Silicon (Si) |
|---|---|---|---|---|---|---|---|---|---|
| Requirement | Balance | 20.0 - 22.5 | 12.5 - 14.5 | 2.5 - 3.5 | 2.0 - 6.0 | ≤ 2.5 | ≤ 0.015 | ≤ 0.50 | ≤ 0.08 |
Key: This precise Ni-Cr-Mo-W balance creates a highly stable passive film, resisting pitting, crevice corrosion, and stress corrosion cracking (SCC).
Alloy C22 Equivalent Grades: Global Material Recognition
C22 elbows are specified under various international standards for identical/similar corrosion performance:
Table 2: Alloy C22 (UNS N06022) International Equivalent Specifications
| Standard System | UNS | EN (Europe) | W.Nr. (DIN) | ISO | JIS (Japan) | GOST (Russia) | Common Trade Names |
|---|---|---|---|---|---|---|---|
| Designation | N06022 | NiCr21Mo14W | 2.4602 | NW 6022 | NW 6022 | ХН60МВЮ | Hastelloy® C-22, INCONEL® alloy 622 |
Note: Equivalency indicates similar corrosion performance; verify specific standard requirements for interchangeability.
Alloy C22 Mechanical Properties: Strength Meets Fabricability
C22 maintains excellent mechanical properties even in aggressive service conditions:
Table 3: ASTM B366/B564 Alloy C22 Typical Room Temperature Mechanical Properties (Wrought & Annealed Condition)
| Property | Tensile Strength (min) | Yield Strength (0.2% Offset, min) | Elongation (in 2" or 50mm, min) | Hardness (Rockwell B, max) |
|---|---|---|---|---|
| Requirement | 690 MPa (100 ksi) | 310 MPa (45 ksi) | 40% | 100 HRB |
| Typical Achieved Value | 780-895 MPa (113-130 ksi) | 360-415 MPa (52-60 ksi) | 55-65% | 75-90 HRB |
Key: High ductility (Elongation) ensures good formability for elbows, while strength exceeds most corrosive service needs.

Table 4: Key Dimensional Tolerances per ASME B16.9 for Alloy C22 Elbows
| Parameter | Tolerance |
|---|---|
| Center-to-End (90° LR) | ±1.6mm (1/16") for NPS ≤ 24", ±3.2mm (1/8") for NPS > 24" |
| Center-to-End (90° SR) | ±1.6mm (1/16") for all NPS |
| Center-to-End (45°) | ±1.6mm (1/16") for NPS ≤ 24", ±3.2mm (1/8") for NPS > 24" |
| Out of Roundness (Ovality) | 1% of Nominal OD max (after welding prep) |
| Wall Thickness | ±12.5% of ordered nominal wall (subject to mill tolerance of raw pipe/tube) |
| Bevel Angle | 37.5° ± 2.5° |
| Bevel Land (Face) | 1.6mm ± 0.8mm (1/16" ± 1/32") |
