Materials and Metallurgical Expertise
Openex routinely works with complex alloys and specialty steels required for high radiation, corrosion, and pressure environments. These materials are sourced from certified nuclear-grade suppliers and subjected to rigorous quality checks.
- Stainless steels: 304L, 316L, 321, 347H, 310S
- Duplex and Super Duplex (2205, 2507) for chloride resistance
- Low-alloy pressure vessel steels: SA-387, SA-203, SA-516
- Nickel-based superalloys: Inconel 600/625, Hastelloy C-276, Monel 400
- Zirconium and titanium (for advanced experimental systems)
- Clad and explosion-bonded plates for core support assemblies
Quality Assurance, Inspection & Traceability
Openex implements a nuclear-qualified quality system aligned with NQA-1, ISO 19443, ASME Section III, and other global nuclear codes. Every step of production is tracked, recorded, and verified through an auditable documentation system.
- WPS/PQR/WPQ documentation for every weld process
- Full Material Traceability Reports (MTRs)
- Non-Destructive Testing (NDT): RT, UT, PT, MT, PMI, VT, and ferrite content
- Dimensional verification using portable CMMs and laser trackers
- Cleanroom assembly inspections for reactor internals
- Mechanical testing: tensile, impact (Charpy), hardness, intergranular corrosion
