Specially designed electrode welding for Super Duplex Stainless steel.
CLASSIFICATION
: AWS/SFA-5.4: E 2553-16
BS 2526 25.6.2Cu.R
BS 2526 25.6.2Cu.R
CHARACTERISTICS :
A fully austenitic stainless steel electrodes weld metal is 20 Cr, 34 Ni, 2.50 Mo, 3.50 Cu with Nb added to improve resistance to inter-granular corrosion. These alloying are primarily used to weld base metals of similar composition for applications where resistance to severe corrosion is required.
APPLICATION :
- Mostly castings materials to be welded, such as ASTM A351, A744 (CD4MCu), UNS 393370, ASTM A 240 (wrought ), UNS 532550, BS 3146-ANC 21, BS 3100 332 C13.
- Proprietary alloys: Creusot Uranus 55, 50M
- APV Lake and Elliot DPH, Langley alloys Ferralium
- Suitable for pumps, valves, process equipment in offshore oil & Gas industries, pulp & paper, textile industries , chemical and petrochemical plants,.
RE-DRY CONDITION :
Re-Dry the electrode at 250°C for 1 hrs before use.
