Material Name | Key Properties | Alloy Elements & Functions | Typical Applications |
|---|---|---|---|
| 6928 Alloy Steel | High strength, seawater corrosion resistance | Cr (forms oxide film), Mo (enhances pitting resistance) | High-pressure vessels, seawater pipelines |
| NiFeCr12Mo | Chloride ion resistance, stress corrosion cracking resistance | Cr-Mo synergy (strengthens passive layer), Ni (improves toughness) | Deep-sea valves, heat exchanger components |
| EH40/DH36 Ship Plate Steel | High toughness, excellent weldability | Microalloying design (Ti-V refines grains), Mn (enhances low-temperature toughness) | Ship hulls, main frames of offshore platforms |
| N10276 (Hastelloy C-276) | Extreme corrosion resistance (acids/high temps), crevice corrosion resistance | Ni-Mo-Cr ternary system (Ni matrix resists corrosion, Mo counters reducing acids, Cr resists oxidizing media) | Subsea acidic oil/gas pipelines, reactors |
| Incoloy 926 | High-temperature corrosion resistance, chloride stress corrosion resistance | Fe-Ni-Cr matrix (25% Cr boosts oxidation resistance), Mo (6%) + N (0.2%) synergize against pitting | Seawater desalination units, high-temperature reactors |
