■ Technical Specifications

Material	Hastelloy B3 (Nickel-Molybdenum Solid Solution Alloy)
Standard / Classification	UNS N10675 \| DIN 2.4600 \| Alloy B-3 Density: 9.22 g/cm³ Melting Range: 1370 - 1418°C (2500 - 2585°F)
Mechanical Properties	Tensile Strength: ≥ 760 MPa (110 ksi) Yield Strength (0.2% Offset): ≥ 350 MPa (51 ksi) Elongation (%): ≥ 40% Hardness (Rockwell B): ≤ 100 HRB
Chemical Composition (%)	Ni: 65.0 Min (Balance) \| Mo: 27.0 - 32.0 \| Cr: 1.5 - 3.0 \| Fe: 1.5 - 3.0 \| W: 3.0 Max \| Co: 3.0 Max \| Mn: 3.0 Max \| Al: 0.50 Max \| Ti: 0.20 Max \| C: 0.01 Max \| Si: 0.10 Max
Manufacturing Specification	ASTM F468 (Standard Specification for Nonferrous Bolts, Hex Cap Screws, Socket Head Cap Screws, and Studs for General Use). Dimensional tolerances strictly follow DIN 975 / DIN 976 and ASME B18.31.2 for continuous threading. Material conforms to ASTM B335.
Thread	Metric ISO standard. Available as Fully Threaded (Continuous Thread), Double End Studs, and Tap End Studs. Class 6g tolerance for standard metric threads.
Properties & Applications	Engineered for critical flanged connections in advanced chemical processing environments. Hastelloy B3 stud bolts provide the same exceptional resistance to hydrochloric, acetic, and phosphoric acids as B2, but with vastly superior thermal stability. This prevents embrittlement and stress corrosion cracking when exposed to intermediate temperatures during operations. Important Engineering Note: Hastelloy B3 fasteners should not be utilized in oxidizing media or where oxidizing contaminants (like ferric or cupric salts) might form.
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 respective Grade identifier.
Qualification & Acceptance	Independently tested for thread tolerance, hardness, chemical analysis, and supplied with EN 10204 Type 3.1 Material Test Certification.
