Methods to Reduce the Occurrence of Strain-Age Embrittlement
There are several ways to reduce the occurrence of strain-age embrittlement, but all methods focus on one aspect – reducing the stresses induced into the steel
Strain-Age Embrittlement
The most common type of embrittlement encountered in the hot-dip galvanizing process is strain-age embrittlement. Strain-ageing is a process where steel becomes very brittle in
Hydrogen Embrittlement
Hydrogen embrittlement occurs when steel cracks due to hydrogen that is trapped between the grains of the steel. Although steel commonly absorbs hydrogen during the
Who Is Responsible for Avoiding Embrittlement?
ASTM A143/A143M spells out who is responsible for avoiding embrittlement. The responsibility lies on the designer, fabricator, and the galvanizer, but each party
How can hot-dip steel be dulled or deglared?
Some types of steel come out of the kettle with a matte gray finish and others come out of the kettle with a bright and
Does magnesium chloride corrode galvanized steel?
Magnesium chloride can aggressively attack many types of steel, including galvanized steel. Wet magnesium chloride is more aggressive than dry. Magnesium chloride should not be
Rough Surface on Overlapped Area of Progressively Dipped Steel
Why does the overlapped area on some progressively dipped steel have a rougher surface and thicker zinc coating than the other area of the same
Zinc Skimmings
Zinc skimming deposits are usually caused when there is no access to remove the zinc skimmings during the withdrawal of the steel from the galvanizing
Weeping Weld
Weeping welds stain the zinc surface at the welded connections on the steel. Caused by entrapped cleaning solutions that penetrate the space between the two
Surface Contaminant
Surface contaminants will create an ungalvanized area where the contaminant was originally located, and a surface defect may occur. This can be caused by paint,
