Abstract
PURPOSE:To obtain a superior metallic padding material for gap corrosion prevention for austenitic stainless steel in the sea by using Ni as an essential component and by containing specific amounts of Cr and Mo or Nb, Ta, Ti, etc. CONSTITUTION:This is Ni-Cr-Mo alloy consisting essentially of Ni and containing 20-35% or and 3-8% Mo or Ni group alloy containing no less than one kind of Nb, Ta and Ti more than ten times as much as the C contents in total (providing that in case of Ni, 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 gap corrosion of the austenitic stainless steel used in the sea.
