22、nation is the term by which the minimum triple spot, total both sides coating weight mass is specified. Because of the many variables and changingconditions that are characteristic of continuous hot-dip coating lines, the zinc or zinc-iron alloy coating is not always evenly divided between the two s
23、urfaces of a coatedsheet; nor is it always evenly distributed from edge to edge. However, the minimum triple-spot average coating weight (mass) on any one side shall not be less than 40 %of the single-spot requirement.BAs it is an established fact that the atmospheric corrosion resistance of zinc or
24、 zinc-iron alloy-coated sheet products is a direct function of coating thickness (weight(mass), the selection of thinner (lighter) coating designations will result in almost linearly reduced corrosion performance of the coating. For example, heavier galvanizedcoatings perform adequately in bold atmo
25、spheric exposure whereas the lighter coatings are often further coated with paint or a similar barrier coating for increasedcorrosion resistance. Because of this relationship, products carrying the statement “meets ASTM A653/A653Mrequirements” should also specify the particular coatingdesignation.CI
26、nternational Standard, ISO 3575, continuous hot-dip zinc-coated carbon steel sheet contains Z100 and Z200 designations and does not specify a ZF75 coating.DNo minimum means that there are no established minimum requirements for triple- and single-spot tests.A653/A653M 1523.2.1 bake hardenable steel,

37、eet.3.2.8.1 DiscussionZinc-iron alloy coating is composed entirely of inter-metallic alloys. It is typically produced by subjecting the hot-dip zinc-coatedA653/A653M 153steel sheet to a thermal treatment after it emerges from the molten zinc bath. This type of coating is suitable for immediate paint
38、ingwithout further treatment except normal cleaning (refer to Guide D7396). The lack of ductility of the alloy coating presents apotential for powdering, etc.4.
