DETAILS
Features/Characteristics
SME 2209-16 Electrode the nominal composition of this weld metal is 22.5 Cr, 9.5 Ni, 3 Mo, 0.15 N. Weld metal deposited by these electrodes has “duplex” microstructure consisting of an austenite-ferrite matrix. Weld metal deposited by SME2209 Electrodes combines increased tensile strength with improved resistance to pitting corrosive attack and to stress corrosion cracking.
SME 2209-16 Welding Rod Uses/Applications
- SME 2209-16 used for Offshore oil and gas, chemical, petrochemical.
- Used for welding duplex stainless steels having Cr< 25% and other grades like UNS 32205, UNS 31803, etc.
- Suitability to Welding of 2205 Stainless Steels
- Off shore Platforms and Chemical industries.
Re-drying Conditions
To obtain best results re dry the electrodes at 300 °C for 1 hour (Optionally available in vacuum-packed condition, re-drying not required in this packaging).
