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 has different responsibilities. Choosing steel appropriate for the practices normally encountered in the galvanizing process and designing the product to avoid embrittlement are the responsibilities of the designer. The fabricator is responsible for using suitable fabrication procedures to avoid embrittlement, such as following minimum bend recommendations and reaming holes on thicker steel. And finally, the galvanizer is responsible for employing proper pickling and galvanizing procedures during the galvanizing operation.
Communication between the designer, fabricator, and galvanizer is key. Communication throughout the design, fabrication, and galvanizing processes ensures best practices are used throughout and thus minimize the possibility of embrittlement.
