Metal Working and Low Alloys
 


The 200 Series - Fabrication and maintenance of mild, low-alloy and high-strength steel.
 


Polytec® 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® 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® 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® 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® 205 (AC/DC) - This product, with outstanding operating characteristics, is an upgrading of Polytec® 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® 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® 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® 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® 225-T CM - Similar to Polytec® 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
