Bohler EN: W 20 16 3 Mn NL Thermanit 19/15 H Stainless Steel TIG Welding Rods
TIG rod of W 20 16 3 Mn N L / ER316L (mod.) type for joining and surfacing applications with matching and similar austenitic CrNi(N) and CrNiMo(Mn,N)-steels and cast steel grades. Non-magnetic (relative magnetic permeability in fi eld of 8000 A/m max. 1.01). Particularly suited for corrosion conditions in urea synthesis plants for welding work on steel X2CrNiMo18-13-3. Corrosion resistance is similar to low carbon CrNiMo(Mn,N)-steels and cast steel grades. Seawater resistant and good resistance to nitric acid. Huey test in acc. to ASTM A 262-64: max. 3.3 μm / 48 h (0.54 g/m 2 h), selective attack max. 200 μm. Service temperature max. 350ºC.
