MAC Stain E101 ELC
AWS E308L
Descriptions & Applications:
High quality rutile type stainless steel electrode for welding low carbon 19% Chromium, 9% Nickel stainless steel. The extra low carbon content provides improved corrosion resistance and notch toughness at low temperatures. Wide usage in the pressure vessel, process plant, dairy and food industries, also suitable for cryogenic applications where high notch toughness at sub-zero temperatures is required. Although the electrode is primarily for welding steels of the AISI 304L and 308L types, it may also be used for welding the higher carbon types 304 and 308. In applications where the operating temperature does not exceed 400° C the electrode may also be used for welding type 347 steels.
