EDGE ROLLING (EDGE CONDITIONING)
Rolling a strip of steel to smooth the edges.  By removing the burr off the coil, it is safer for
customers to manipulate.
****

ELECTRIC ARC FURNACE (EAF)
Steel-making furnace where scrap is generally 100% of the charge.  Heat is supplied from
electricity that arcs from the graphite electrodes to the metal bath.  Furnaces may be either an
alternating current (AC) or direct current (DC).  DC units consume less energy and fewer
electrodes, but they are more expensive.  
****

ELECTRIC RESISTANCE WELDED (ERW) PIPE
Pipe made from strips of hot-rolled steel which are passed through forming rolls and welded.  
While seamless pipe is traditionally stronger and more expensive than comparable ERW pipe,
ERW technology is improving and the technique now accounts for approximately 48% of OCTG
shipments by tonnage.

ELECTRICAL STEEL
(See Silicon Electrical Steel)
****

ELECTROLYTIC GALVANIZED 1
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.
****

ELECTROLYTIC TIN COATED SHEETS (ETCS) 1
Cold rolled sheets coated with tin by electro-deposition through an acid or alkaline process.
****

ELECTROLYTIC TIN PLATE (ETP) 1
1        Light-gauge, low-carbon, cold reduced steel on which tin has been electrodeposited.

2        Black plate coated with Tin Sn electron deposition.
****

ELECTROPOLISHING 3
The process used on stainless steel tubing and fittings to simultaneously smooth, brighten,
clean, and passivate the interior surfaces of these components.  Electropolishing is an
electrochemical removal process that selectively removes a thin layer of metal, including
surface flaws and imbedded impurities.  Electropolishing is a required surface treatment
process for all ultra high-purity components used in the gas distribution systems of
semiconductor manufacturers worldwide and many sterile water distribution systems of
pharmaceutical and biotechnology companies.

EXOTIC ALLOYS   
Zirconium, niobium, hafnium, and tantalum products.
****

EXTRUSION
The process of shaping material by forcing it to flow through a shaped opening in a die.
