Metal Properties Flashcards
thickness of large steel members typ expressed in
fractions/decimals of inch
origin in weight per sqft of metal
gage
used to describe sheet steel,
and nonferrous metals,
of tubing, strips + sheets.
gage
bc today gage is approx. of metals thickness, best practice is
call out thickness is decimals of in.
mild electric current between the two metals,
corroding one, leaving other intact.
most severe in humid, marine environments.
electrolysis
corrosion of dissimilar metals in contact,
w presence of electrolyte
galvanic action
two further apart on galvanic action list
