Stainless Steel Electrodes - Prenox-D2 /Welinox 309 |
Characteristics :
PRENOX-D2 is an extra low carbon, medium heavy coated, rutile based, all position austenitic type electrode for welding of low carbon 18/8/3 Cr/Ni/Mo stainless steels. Controlled ferrite content of 4-8% gives maximum resistance to stress corrosion cracking, hot cracking and chemical corrosion at high temperatures upto 8500C. The Mo content makes it resistant to corrosive agents of reducing nature. The weld metal has excellent creep strength and is of radiographic quality.
|
Applications :
For welding AISI 309 Stainless steel with 25 Cr/12Ni, Straight chrome steels for joining stainless steel to mild steel, Low alloy steel, Carbon steel, for stainless steel Castings and for overlays on Mild Steel to improve its wear and corrosion resistance.
