<p>PURPOSE:To obtain a superior metallic padding material for preventing the gap corrosion of austenitic stainless steel in the sea by using Ni as an essential component and by containing a specific amount of one kind of Cr, Mo and Fe, and Si and B or by further containing Nb, Ta, Ti, etc. CONSTITUTION:This is alloy consisting essentially of Ni and containing one kind or two kinds of 20-35% Cr, 3-8% Mo, <25% Fe, and 1-4% Si and 1-4% B or Ni group alloy further containing not less than one kind of Nb, Ta and Ti more than ten times as much as the C contents (providing that in case of Ti, the double of its contents should be more than ten times the C contents). This shows superior characteristics as a metallic padding material for preventing the gap corrosion of austenitic stainless steel used in the sea.</p> |
