Classification:

AWS/SFA-5.4: E 2209-16
DIN E 22 9 3 LR 23

Characteristics:

Ratna 2093L is a medium heavy coated, all-position electrode depositing a “duplex” microstructure, consisting of a ferrite matrix. The weld metal meets stainless steel requirements for armour steel and exhibits excellent corrosion resistance, especially against atmosphere, seawater, and weak acids.

Application:

• Joining stainless steel to carbon steel.
• Depositing austenitic weld metal on higher carbon steel and armour steel.
• Weld metal combines increased tensile strength and resistance to pitting corrosion and stress corrosion cracking, suitable for demanding service conditions.

Re-Dry Condition:

Re-Dry the electrode at 250°C for 1 hrs before use.
