Stainless Steel Welding Electrode E BK 308MoL
Electrode with 14% ferrite, is recommended for joining steel to stainless steel. Joining and surfacing carbon steel, spring steel, tool steel, manganese steel, and stainless steel (AISI 304, 316, 1.4401, 1.4435). Heat resistant up to 900 °C (1650 °F); Corrosion and wear-resistant; High recovery (165 %). The electrode does not become red-hot and can be entirely used even at a high current. L8000 welds with a very smooth arc and has a self-releasing slag. For carbon steel to stainless steel joints, the deposit is free of martensite up to dilution levels of 13%.
Applications
Welding of flanges to stainless steel tubes. Surfacing track links. Welding wear resistant plates of unknown analysis. Applying stainless protective layers on mild steel. Base layer for hard facings.
