DESCRIPTION AND APPLICATION
SELECTARC INOX 316MnNB is a basic coated, fully austenitic stainless steel electrode containing low carbon as well as molybdenum, manganese, and nitrogen. The weld metal is extremely corrosion resistant, especially in seawater and nitric acid environments, and provides high resistance to wet corrosion up to +350 °C.
The electrode provides a stable arc, well-controlled weld pool, moderate slag, and a smooth weld profile.
It is especially suitable for urea (amide) production plants, as well as for cryogenic steels with 3.5–5% Ni content, where high mechanical strength and corrosion resistance are required.
