E.C.A. Number
Engineering Corporation of America -- This is the computerized
annealing sequence number used by the Firing Model.
Easy Open End
A convenience feature can end designed to be opened by utilizing an
integral tab opener to tear the container lid along a tear line formed
in the lid. The patented WEIR-OPEN end is designed so that after the
container is opened, safe edges remain on the removable panel portion
torn off from the lid body and on the rim remaining on the container.
This is accomplished by shielding the residual tear line metal with
multi-layer metal folds.
Edge Break
A condition caused by an uneven roll surface. It is seen on the edges
of a coil, not across the full width of the coil.
Edge Buckle
Edge buckle is similar to center buckle except that the condition
occurs in one, or both edges, of the strip and is generally confined
to a narrow portion of the width.
Edge Buildup
Condition that results when burred or damaged plate causes the edge of
the coil to be higher in coating than the center of the coil.
Edge Wave
A condition in the band of steel where the edges (in the direction of
rolling) are longer than the center.
Elastic Deformation
Stretching of the material below the point at which a permanent "set"
takes place. That is, in the range where the metal acts spring-like or
elastic.
Electrolytic Galvanized (Weirzin)
Cold Rolled or Black Plate to which a coating of zinc is applied by
electro-deposition; used for applications in which corrosion
resistance and paintability is a primary concern.
ETCS
See Electrolytic Tin Coated Sheets. |

Electrolytic Tin Coated Sheets
(ETCS)
Cold rolled sheet coated with tin by electrodeposition through an acid
or alkaline process.
Electrolytic Tin Plate (ETP)
1.
Light-gauge, low-carbon, cold reduced steel on which tin has been
electrodeposited. 2. Black plate coated with Tin Sn electron
deposition.
Elongation
1.
This term is sued on orders specifying tensile test on which a minimum
elongation between give points and distances has to be met. This
elongation is expressed as percent of stretch over a given length, i.
e. 25% elongation in 2 inches. 2. Total plastic strain before
fracture, measured as a percent or axial strain during tensile
testing.
Embossing
A coating defect consisting of the crawling or dewetting condition
where the wet film recedes and forms a raised (in relief) impression.
Enamel
Organic material, which is applied in a film to protect or decorate
aluminum, tinplate, blackplate or paper.
Epoxy Amino
Clear thermosetting coating with a combination epoxy resin and amino
resin to give adhesion, flexibility and toughness. They offer good
chemical and solvent resistance.
Epoxy Phenolic
Physical blends of epoxy and phenolic resins. Gold thermosetting
coating with a combination of epoxy resin and amino resin to give
adhesion, flexibility and toughness. They offer good chemical and
solvent resistance.
Etching
In metallography, the process of revealing structural details by the
preferential attack of reagents on a metal surface.
