This heavy hex nut is forged and machined from 2205 duplex stainless steel, featuring mixed austenite and ferrite microstructure. It delivers high mechanical strength and excellent anti-fatigue performance. It provides outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. The precisely machined threads ensure high fitting accuracy, stable locking and anti-loosening property.

Widely applied in offshore wind power, offshore platforms, steel bridges, mining machinery, railway projects and heavy engineering equipment for harsh working conditions. Suitable for high salt spray, humid and heavily corrosive environments. Match with 2205 bolts of the same material to form a complete fastener assembly for long-term reliable connection.

1. Higher yield strength than conventional 304 / 316L stainless steel;
2. Superior chloride corrosion resistance, ideal for marine and coastal salt-laden environments;
3. Precision rolled threads with regular profile for smooth assembly;
4. Forged dense structure, vibration and fatigue resistant, perfect for heavy-load dynamic equipment.
