3. Designing parts for galvanizing
3.1 Steel selection
The results obtained during hot-dip galvanizing depend in part on the steels used, and in particular on their chemical composition. When steel is immersed in liquid zinc, a metallurgical reaction (diffusion) occurs between the zinc and the steel.
Coating formation rate and structure depend on the silicon and phosphorus content of the steel.
The standard NF A 35-503 defines three categories of steel suitable for galvanizing (table 4 ). When ordering, please specify the standard reference NF A 35-503 and, if necessary,...
