Title
Standard Practice for Safeguarding Against Embrittlement of Hot-Dip Galvanized Structural Steel Products and Procedure for Detecting Embrittlement
ASTM International
Publication Date:
May 1, 2007
Scope:
This practice covers procedures that can be followed to
safeguard against the possible embrittlement of steel hot-dip
galvanized after fabrication, and outlines test procedures for
detecting embrittlement. Conditions of fabrication may induce a
susceptibility to embrittlement in certain steels that can be
accelerated by galvanizing. Embrittlement is not a common
occurrence, however, and this discussion does not imply that
galvanizing increases embrittlement where good fabricating and
galvanizing procedures are employed. Where history has shown that
for specific steels, processes and galvanizing procedures have been
satisfactory, this history will serve as an indication that no
embrittlement problem is to be expected for those steels,
processes, and galvanizing procedures.
This practice is applicable in either inch-pounds or SI units.
Inch-pounds and SI units are not necessarily exact equivalents.
Within the text of this practice and where appropriate, SI units
are shown in brackets.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
