Hiduron 130 Primary Applications
- Subsea hydraulic and electrical connectors: flying-lead, stab-plate, umbilical termination bodies.
- Marine and offshore bolting: hex bolts, stud bolts, heavy hex bolts in seawater service.
- Pump shafts, valve spindles, mechanical seal faces: anti-galling, corrosion-resistant matrix.
- Aerospace electromagnetic-sensitive bolting: DTD 900/4805 origin spec, mu_r below 1.005.
- General Cu-Ni-Al replacements: where 70/30 cupronickel lacks the strength and Monel K-500 is excluded by NACE or magnetic limits.

EN 10204 Certification and Inspection
Every Hiduron 130 and Hiduron 191 stock and finished fastener ships with EN 10204 type 3.1 mill test certificate as standard. Type 3.2 third-party witness by Lloyd's Register, DNV, BV, SGS or TUV is supplied on call-out and is standard practice on naval and subsea procurement orders. The certificate carries the melt heat number, full chemical analysis to the controlling specification, solution-anneal plus age cycle parameters, tensile and yield results, hardness, Charpy V impact result where called out, and the dimensional report. For Hiduron 191 sour-service orders, an additional NACE MR0175 hardness certificate confirms that every test piece reads below the 286 HBW (28 HRC) limit.
