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
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
Is hot-dip galvanized steel considered anti-sparking?
Yes, hot-dip galvanized coatings are anti-sparking and nonincendiary as are most zinc coatings. The exception is zinc coating alloys that have 30 to 55% aluminum. It is
How Corrosive is Propylene Glycol to Hot-Dip Galvanized Steel?
According to Frank Porter’s book, Corrosion Resistance of Zinc and Zinc Alloys, propylene glycol will corrode zinc-coated steel less than 0.5 mil per year. Please
How much does galvanizing cost?
To compare the cost of hot-dip galvanizing to other protective coatings, please visit http://www.galvanizingcost.com. To get prices for galvanizing from galvanizers in
What types of metals will not galvanize?
There are many types of materials that will not develop a galvanized coating. Iron is necessary for a galvanizing reaction to happen, so if you
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
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
Overlapped Surfaces
It is important to properly vent overlapping and contacting surfaces to prevent trapped moisture (from pickling or flux solution used in the galvanizing process) or
