PRODUCT TYPE : ALL POSITION ELECTRODE FOR STAINLESS STEEL
DESCRIPTION : S 628L
APPLICATIONS : A 18 / 8 Cr / Ni alloy with extra low carbon content ( C<0.03% ). For grades 304L, 301, 302, 303, 308, 321, 347 and corresponding E.I.C.grades. Use on typical brewery, food and pharmaceutical equipment, also for architectural fabrication.
MICROSTRUCTURE : Austenite with 3-9% ferrite. Typical ferrite number is 6
CHARACTERISTICS : The high quality coating allows the electrode to run at very low amperages to avoid distortion but still give strong clean spatter – free welds. Controlled silicon content provides maximum corrosion/cracking resistance.
WELDING TECHNIQUES : Material to be welded should be clean of all contaminants. Maintain a short arc and use stringer beads rather than a weave technique.
