■ 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). Material conforms to ASTM B335 (Standard Specification for Nickel-Molybdenum Alloy Rod).
Thread	Metric ISO standard. Available in full thread (DIN 933) and half thread (DIN 931) configurations. Class 6g tolerance for standard metric threads.
Properties & Applications	Hastelloy B3 is an upgrade over B2, offering the same outstanding resistance to hydrochloric acid and other strongly reducing media, but with vastly superior thermal stability. This means B3 bolts are far less susceptible to embrittlement and stress corrosion cracking during high-temperature exposure or manufacturing processes. Ideal for severe chemical processing applications, including acetic, formic, and phosphoric acids. Note: Like B2, Hastelloy B3 fasteners should not be used in the presence of oxidizing media or oxidizing salts.
Marking	In accordance with ASTM F468. Fastener heads are forged with Manufacturer Identification (Ananka) and the respective Grade identifier.
Qualification & Acceptance	Independently tested for hardness, thread tolerance, chemical analysis, and supplied with EN 10204 Type 3.1 Material Test Certification.
