■ Mechanical Properties & Yield Strength
Hastelloy C22 Fasteners retain excellent mechanical integrity and ductility, allowing them to excel in systems with severe temperature fluctuations and corrosive media. Below are the standard mechanical properties:
| Tensile Strength (Min) | Yield Strength 0.2% Offset (Min) | Elongation (%) | Density |
|---|---|---|---|
| 100 ksi (690 MPa) | 45 ksi (310 MPa) | 45% Min | 8.69 g/cm³ |
■ Fine Chemicals, Pharmaceuticals & EPC Applications
Thanks to their optimal blend of chromium (22%) and molybdenum (13%), Hastelloy C22 components are exceptionally resistant to mixed acid streams, oxidizing aqueous media, and wet chlorine environments.
- Pharmaceuticals & Fine Chemicals: Fasteners for hygienic processing equipment, reactors, and high-purity chemical storage where preventing contamination is critical.
- Pollution Control: Flue gas desulfurization (FGD) scrubbers, sulfur dioxide cooling towers, and chlorination systems.
- Chemical Processing: Heat exchangers and piping systems exposed to oxidizing acid mixtures (e.g., nitric, sulfuric, and phosphoric acids).
- Waste Water Treatment: Equipment handling highly corrosive, mixed waste streams and oxidizing/reducing agents.
■ Quality Assurance & MTC Downloads
As a primary manufacturer based in Mumbai, our quality control goes beyond standard chemical analysis. We conduct rigorous first-hand testing on all Hastelloy C22 Fasteners to ensure they meet the stringent safety requirements of EPC contractors and pharmaceutical plant operators.
- Ultrasonic Testing (UT): Internal flaw detection performed on raw billets prior to machining.
- Destructive Testing: In-house tensile, yield, and elongation testing to verify structural integrity.
- PMI (Positive Material Identification): 100% optical emission spectroscopy scanning prior to dispatch to guarantee critical chromium and molybdenum levels.
