Key Advantages of Hastelloy X Threaded Rods
High-Heat Resistance
Retains strong clamping force and resists scaling in continuous high-temperature service up to 1200 °C.
Resists Creep & Sag
Molybdenum and Iron addition prevents studs from stretching or loosening under high heat and continuous heavy loads.
Furnace Gas Protection
Fights off carbon absorption and damage from harsh combustion gases, nitriding, and furnace atmospheres.
Smooth & Secure Threading
Precision roll-threaded construction prevents thread stripping and jamming under thermal expansion.
Quality Testing & Inspection
Aurum Overseas subjects every shipment to full Quality Assurance protocols to ensure adherence to global aerospace and petrochemical fastener standards:
- Positive Material Identification (PMI): Spectro / XRF analysis confirming exact elemental composition per ASTM B572 specs.
- Dimensional & Thread Pitch Inspection: Go/No-Go gage testing and optical comparator checks ensuring 2A/3A and 6g thread fit tolerances.
- Mechanical Batch Testing: Tensile strength, yield strength, and elongation verification certified via EN 10204 3.1 Material Test Reports.
- Optional Specialized Inspections: High-temperature stress rupture testing, dye penetrant inspection, or ultrasonic NDT upon customer request.
