ASTM & Other Specifications
What are the differences between ASTM A123/A123M and ASTM A385?
ASTM A123/A123M give the requirements for inspecting the final hot-dip galvanized product, including coating thicknesses and sampling requirements. ASTM A385 gives information on
How long does it take to convert Chromium VI to Chromium III on galvanized steel?
Some galvanized steel is dipped into chromium quenches after hot-dip galvanizing. The chromium creates a passivated surface on the galvanized coating that prevents wet storage
Is it possible to have steel with chemistry that is 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

Can non-members get technical support from the AGA?
One of the benefits of being a member of the American Galvanizers Association (AGA) for galvanizers is free unlimited technical support. The AGA technical staff
Can 4130 steel be successfully galvanized?
4130 steel is a chromoly steel. Steels of this chemistry have presented some adherence problems in the past when galvanized. The galvanized coating developed in some
Necessary design and fabrication steps to ensure the highest quality hot-dip galvanized coatings
ASTM A385 Standard Practice for Providing High-Quality Zinc Coatings (Hot-Dip) identifies good practices to utilize to obtain a zinc coating to meet your expectations. The
Embrittlement of Hot-dip Galvanized Steel and How to Avoid It
ASTM A143 Standard Practice for Safeguarding Against Embrittlemnet of Hot-Dip Galvanized Structural Steel Products defines the practice of procedures that can be followed to safeguard
Practices to avoid warpage and distortion of hot-dip galvanized articles
ASTM A384 Standard Practice for Safeguarding Against Warpage and Distortion During Hot-Dip Galvanizing of Steel Assemblies identifies factors and types of assemblies and weldments prone
Measuring Zinc Coating Thickness of Hot-dip Galvanized Steel
Coating thickness is tested by using a magnetic thickness gauge. There are three types of magnetic thickness gauges: pencil-style, banana-style, and electronic. Electronic thickness gauges
