4. Performance Characteristics
4.1 Exceptional Corrosion Resistance
Hastelloy C22 nickel alloy round bar exhibits outstanding corrosion resistance in a wide range of aggressive media. It has excellent resistance to both oxidizing and reducing acids, such as sulfuric acid, hydrochloric acid, nitric acid, and acetic acid. Even in mixed acid environments with high concentrations and high temperatures, it can maintain good corrosion resistance, effectively preventing pitting, crevice corrosion, and intergranular corrosion. This makes it an ideal choice for chemical processing equipment, oil and gas exploration and production components, and other applications exposed to corrosive media.
4.2 Excellent High - Temperature Performance
With its unique alloy composition, the round bar shows excellent high - temperature strength and oxidation resistance. It can operate stably for a long time in high - temperature environments up to 1093°C, without significant degradation in mechanical properties or severe oxidation. Moreover, it has good creep and stress rupture resistance, which can withstand the long - term effects of high - temperature and constant loads, making it suitable for high - temperature furnace components, aerospace engine parts, and other high - temperature applications.
4.3 Good Mechanical Processing Performance
Despite its high strength and excellent corrosion resistance, Hastelloy C22 nickel alloy round bar still has good mechanical processing performance.

8. Packaging and Transportation
8.1 Packaging
To ensure that the Hastelloy C22 nickel alloy round bar is not damaged during storage and transportation, and to prevent corrosion and contamination, the following packaging methods are adopted:
- Inner Packaging: Each round bar is first wrapped with a layer of moisture - proof plastic film to isolate it from air and moisture, preventing oxidation and corrosion. For small - diameter round bars, they can be bundled into small bundles with plastic straps, and each bundle is wrapped with moisture - proof paper.
- Outer Packaging: The inner - packaged round bars are placed in strong wooden cases or steel crates. The wooden cases are made of high - quality hardwood, which has good load - bearing capacity and impact resistance. The interior of the cases is filled with soft materials (such as foam plastic) to prevent the round bars from colliding with each other during transportation. The steel crates are made of thick steel plates, which are more durable and suitable for long - distance sea transportation.
- Labeling: Each package is clearly labeled with product information, including product name (Hastelloy C22 nickel alloy round bar), grade (Alloy 2.4602 / UNS N06022), diameter, length, quantity, batch number, production date, manufacturer's name, and contact information. In addition, labels such as "Moisture - proof", "Shock - proof", "No Heavy Pressure", and "Direction of Placement" are also attached to remind the handlers to pay attention during transportation and storage.
8.2 Transportation
- Mode of Transportation: According to the quantity of products, destination, and customer requirements, appropriate transportation methods are selected, including road transportation, railway transportation, sea transportation, and air transportation. For large - quantity and long - distance transportation, sea transportation is usually chosen, which is cost - effective. For urgent orders or small - quantity products, air transportation can be selected to ensure the timely delivery of products. Road transportation and railway transportation are suitable for short - distance and medium - distance transportation, with the advantages of flexibility and fast delivery.
- Transportation Conditions: During transportation, the packages should be placed stably to avoid tilting, collision, and extrusion. The transportation vehicles or containers should be clean, dry, and free from corrosive substances. In case of rainy or snowy weather, rainproof and moisture - proof measures should be taken to prevent the packages from getting wet. For sea transportation, the containers should be checked for tightness to prevent seawater from entering.
- Transportation Documentation: Complete transportation documentation is provided, including commercial invoice, packing list, bill of lading (for sea transportation) or air waybill (for air transportation), certificate of quality, and certificate of origin. These documents are necessary for customs clearance and product acceptance at the destination, ensuring the smooth progress of the transportation process.
