| Manufacturing Specification |
ASTM F468 (Standard Specification for Nonferrous Bolts, Hex Cap Screws, Socket Head Cap Screws, and Studs for General Use). Dimensional tolerances follow DIN 975 / DIN 976 and ASME B18.31.2 for continuous threading. |
| Thread |
Metric ISO standard. Available as Fully Threaded (Continuous Thread), Double End Studs, and Tap End Studs. |
| Properties & Applications |
Critical for high-pressure flanged connections in the most severe environments. Hastelloy C-22 offers better overall corrosion resistance than C-276, providing outstanding protection against oxidizing and reducing aqueous media, as well as exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. |
| Marking |
In accordance with ASTM F468. Standard markings for continuous thread studs are typically applied to the end faces, including Manufacturer Identification (Ananka) and the Grade identifier. |
| Qualification & Acceptance |
Independently tested for thread tolerance, hardness, chemical analysis, and supplied with EN 10204 Type 3.1 Material Test Certification. |
