D&H 309L

AWS: SFA 5.4 E309L-16 IS: 5206 E23.12L R16 EN ISO CODE: 3581-A E (23 12L) R 3 2

D&H 309L is a stainless steel electrode depositing an extra low carbon 24Cr - 12Ni weld metal. The weld metal has excellent mechanical properties and possesses good oxidation and scaling resistance at elevated temperatures. Ideally suited for welding stainless steels, wrought and cast materials of similar composition, welding of 18/8 type stainless steels to carbon steels for buffer layers, for welding clad side of 18/8 clad stainless steels, etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.

2. Use short arc and stringer bead.


NOTE : D&H 309L-15 conforming to AWS E309L-15 is also available.
