| Chemical Composition (%) |
Ni: Balance | Mo: 15.0 - 17.0 | Cr: 14.5 - 16.5 | Fe: 4.0 - 7.0 | W: 3.0 - 4.5 | C: 0.01 Max | Mn: 1.0 Max | V: 0.35 Max |
| 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. The high molybdenum and chromium content provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in severe environments like chemical processing, pollution control (FGD systems), and pulp/paper production. |
| 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. |
