Our inventory of ASTM B574 UNS N06455 Threaded Bars utilizes a low-carbon chemistry stabilized with Titanium (up to 0.7%) and low Iron content (3.0% max). This metallurgical formulation prevents the formation of intermetallic phases between 650 °C and 1040 °C, guaranteeing structural integrity in welded assemblies.
Built for chlorination loops, fertilizer vessels, and pickling units, our UNS N06455 Threaded Rods deliver reliable, leak-tight joints. Contact Aurum Overseas for factory quotes, custom cutting, and fast global delivery.

Key Advantages of Hastelloy C4 Threaded Rods
High Thermal Stability
Controlled Titanium additions prevent intermetallic phase precipitation in the heat-affected zone, maintaining post-weld corrosion resistance.
Resistance to Oxidizing & Reducing Media
Balanced Chromium (14–18%) and Molybdenum (14–17%) content provides dual protection against mineral acids, chlorine, and organic solutions.
High Ductility & Formability
An elongation rating of 55% enables exceptional impact resistance and thermal fatigue toughness under heavy dynamic loads.
Precision Roll-Threaded Quality
Smooth thread flanks reduce friction during assembly, preventing galling and securing joint integrity under continuous pressure.
Quality Testing & Inspection
Aurum Overseas subjects every shipment to stringent Quality Assurance protocol to ensure compliance with global fastener standards and customer engineering requirements:
- Chemical Verification (PMI): XRF/Spectro chemical analysis validating exact element concentrations per ASTM B574 specs.
- Dimensional & Thread Pitch Inspection: Go/No-Go thread gage testing and optical comparator verification ensuring exact 2A/3A or 6g pitch tolerances.
- Mechanical Batch Testing: Tensile strength, yield strength, and elongation verification backed by EN 10204 3.1 Material Test Reports.
- Optional Specialized Testing: Ultrasonic testing, intergranular corrosion testing (ASTM G28), or proof load testing available upon request.
