EN 1.4462 ist der European designation für 2205 duplex stainless steel — der meiste widely used duplex grade. Es delivers roughly twice der yield strength von 316L mit superior chloride stress corrosion cracking widerstand, making es der standard material für North Sea offshore platform piping, chemical tanker cargo tanks, und desalination evaporator shells.

Frequently Asked Questions
Was welding consumables sind used für 2205 duplex?
Verwenden über-alloyed filler metals (typically 22.8.3L oder 25.10.4L) mit 2-3% higher nickel als der base metal. Dies compensates für der ferrite-promoting effect von rapid weld cooling, ensuring der weld metal achieves der target 40-60% ferrite balance. Pure autogenous welding (nein filler) typically produces übermäßig ferrite (>70%) mit reduced toughness und corrosion widerstand.
