Metal Working and Low Alloys
¡¡
The 200 Series - Fabrication and maintenance
of mild, low-alloy and high-strength steel.
¡¡
Polytec¢ç 200 (AC/DC) - A versatile,
general-purpose, all-position low-alloy steel electrode
designed and developed for production and maintenance
welding of mild steel. Uses include fabrication and
maintenance welding of sheet metal ducts, tanks,
culverts, pipe, plate and angle iron.
Specification: NA
Available forms: E , FC , TIG , MIG
¡¡
Polytec¢ç 201 (AC/DC) - An all-position,
low-alloy electrode designed specifically for deep
penetration and porosity-free weld deposits on
components contaminated by dirt, rust and grease. Uses
include fabrication and maintenance welding sheet metal
ducts, tanks, culverts, pipe and angle iron.
Specification: NA
Available forms: E
¡¡
Polytec¢ç 202 (DC-RP) - A low-hydrogen,
chrome/nickel/moly alloy for high-strength,
crack-resistant weld deposits. Uses include the joining
of T-1, HY 80/90 steels and "problem" steels containing
sulphur, graphite or other elements to improve
machinability.
Specification: NA
Available forms: E , FC , TIG , MIG
¡¡
Polytec¢ç 204 (AC/DC) - A high-speed,
medium-penetration iron-powder electrode for steel
fabrication with low spatter, excellent slag removal and
easy re-strike. Uses include all types of mild-steel
fabricating, poor fit-up joining, plate, tanks and
beams.
Specification: NA
Available forms: E
¡¡
Polytec¢ç 205 (AC/DC) - This product, with
outstanding operating characteristics, is an upgrading
of Polytec¢ç 204. It exhibits higher physical properties
and a Rockwell hardness of 23/25. Uses include
high-strength fabrication and buildup or buffer layers
prior to hard-surfacing or overlay applications.
Specification: NA
Available forms: E
¡¡
Polytec¢ç 207-FC - A superior buildup alloy
for carbon and low-alloy steels. Good compressive
strength, and abrasion properties. Also provides an
excellent base for hard-surfacing materials. Uses
include steel-mill roll build-up, wobblers, coupling
boxes, gear teeth, mine-car wheels and tractor rollers
and rails.
Specification: NA
Available forms: FC
¡¡
Polytec¢ç 210 (AC/DC) - A unique alloy
designed to join crack-sensitive sections of 4130 and
4140 steels. Also used for the repair and buildup of
cracked sections of P-20 mold steel. Uses include
buildup, fabrication and low-hardness overlays.
Specification: AWS-E80S D2
Available forms: E , TIG , MIG
¡¡
Polytec¢ç 215-T CM - A versatile,
high-strength chrome/moly alloy used to join and repair
alloys of approximately the same analysis. Other uses
include fabrication of race- and stock-car components,
pressure vessels, high-pressure pipe, cast and wrought
sections of chrome/moly base metal.
Specification: AWS-E80S B2
Available forms: E , TIG , MIG
¡¡
Polytec¢ç 225-T CM - Similar to Polytec¢ç 215-T
CM, except chrome/moly alloy content is increased,
exhibiting higher physical properties. Uses include
fabrication and repair of chome/moly alloys of
approximately the same analysis; power piping and boiler
maintenance.
Specification: AWS-E90S-B3
Available forms: E , TIG , MIG
