Is it possible to have steel with chemistry too good for galvanizing?

It is possible to have steel chemistry with levels of silicon and phosphorus that are too low to meet the minimum thickness levels specified in ASTM A123 and ASTM A153. Very low silicon levels are seen more often on...

Galvanizing small parts, hardware, and fasteners to ASTM A153

ASTM A153 governs zinc coatings applied by the hot-dip process on iron and steel hardware, including nails, bolts, nuts, fasteners, and rods.  The hot-dip galvanizing process for articles galvanized to ASTM A153 is...

Clogged Holes

Clogged holes are a defect caused by molten zinc metal not draining adequately and partially or completely filling holes with excess zinc. Molten zinc will not drain easily from holes less than 3/10” (8mm)...

Clogged Threads

Clogged threads are caused by poor drainage of a threaded section after the product is withdrawn from the galvanizing kettle. Clogged threads, as seen to the left, can be cleaned by using post-galvanizing...

Is there concern about galvanic corrosion when different types of zinc-coated steel are in contact?

There is not a concern of dissimilar metals corrosion (galvanic corrosion) when pairing zinc-coated steel of different types (for example when pairing a hot-dip galvanized bolt with a mechanically galvanized nut). P...
