Definitions

  • the present invention relates to a bath for hot-dip galvanising consisting of alloyed zinc, that is particularly useful for batchwise galvanising steel articles.
  • the aim of the present invention is therefore to provide a bath composition for hot-dip galvanising, which results in a coating thickness of 30 to 50 ⁇ m. Also, the thickness of the intermetallic layer is reduced to approximately 30 to 35 ⁇ m. This induces an increased resistance to stress induced crack formation as required e.g. for critical parts in the automotive industry.
  • the bath contains, by weight, 0.1 to less than 1 % Bi, 0.01 to 0.05 % Al, 0.04 to 0.12 % Ni, up to 0.05 % Mn, the rest being zinc and unavoidable impurities.
  • the bath contains 0.3 to 0.8 % Bi, 0.02 to 0.04 % Al, 0.06 to 0.10 % Ni and up to 0.05 % Mn.
  • a bath composition with 0.5 % Bi, 0.03 % Al and 0.08 % Ni is especially preferred.
  • the galvanising process using the alloy of the invention is particularly suitable for coating low reactivity steel.
  • low reactivity steel is meant steel comprising, by weight, Si and P in such amounts that Si ⁇ 0.03 % and % Si + 2.5 x % P ⁇ 0.09.
