DUPLEX FILLER METAL · CLASSIFICATION-CONTROLLED SOURCING
ER2209 Duplex Welding Consumables
Technical sourcing of ER2209 duplex stainless-steel solid wire and rods for approved welding procedures and project specifications.
MNK-G.S.A coordinates classification, supply form, diameter, packaging, batch documentation and delivery for marine and industrial duplex fabrication requirements.
Classification Identity
- AWS A5.9/A5.9M:2022 covers the classification of bare stainless-steel welding electrodes, wires, strips and rods.
- A current manufacturer product page identifies AWS A5.9 ER2209, EN ISO 14343-A W 22 9 3 N L and EN ISO 14343-B 2209.
- ISO 14343:2025 is the current international classification standard; the 2017 edition is withdrawn.
- ER2209 is a filler classification, not an automatic approval for a base-material grade or fabrication procedure.
