Corrosion-resistant chromium-nickel welding wire ER308LSi

ISO 14343-A-G 19 9 LSi
AWS A5.9: ER308LSi
TERMS OF USE
  • Welding is recommended to be carried out in gas mixtures (Ar+CO2) with direct current of reverse polarity
  • Precision winding ensures steady wire feeding to the welding area. increased wire rigidity allows the use of torch with up to 3 m line
SPECIAL PROPERTIES
  • high resistance to nitric and other acids was noted
  • the low carbon content reduces risks of intergranular corrosion for- mation without the introduction of ferritizers such as niobium and ti- tanium, and the high content of deoxidizers ensures convenience and ease of use in the welding process
  • guaranteed mechanical properties of the deposited metal and in- creased corrosion resistance in aggressive environments at tempera- tures from -196 °C to 350 °C
  • excellent surface condition significantly reduces wire feeding ripples and improves welding stability
ER308LSi corrosion-resistant chromium-nickel welding wire is de- signed for semi-automatic welding of stainless steels of the following grades 03H17N14M2, 03H18N11, 06H18N11, 03H18N10, AISI 304L, AISI 304, AISI 321, AISI 347 and other austenitic steels of class 300. It is wide- ly used in food, pharmaceutical, chemical, woodworking and pulp in- dustries, mechanical engineering, reservoirs and pipelines production.
