Pickling - an overview ScienceDirect Topics

Pickling Pickling refers to the immersion of steel in an acid tank in order to remove the iron oxides or scale from the steel's surface and thus,permit the galvanized coating to form upon immersion of the steel in a molten zinc bath (American Galvanizers Association,2015).From Fundamentals of Geoenvironmental Engineering,2018Performance of Hot-Dip Galvanized Steel Productsimmediately be apparent when the steel is withdrawn from the molten zinc,because the unclean areas will remain uncoated and immediate corrective action must be taken.Surface preparation for galvanizing consists of three steps degreasing,acid pickling,and fluxing.Degreasing American Galvanizers AssociationPeople also askWhat is the American Galvanizers Association?What is the American Galvanizers Association?The American Galvanizers Association (AGA) is a non-profit trade association dedicated to serving the needs of after-fabrication galvanizers,fabricators,specifiers,architects,engineers,and contractors.American Galvanizers Association
