C = 0,03
Si = 0,70
Mn = 0,90
Cr = 18,0
Ni = 13,0
Mo = 2,60
Electrode suitable for welding of stainless steel AISI 316 l.
Excellent corrosion resistance to sulfuric acid and
phosphoric acid by. Suitable for applications in the food
industry, paper and pulp, textile. Intercrystalline corrosion
is not even above 300 degrees Celsius, due to extra low
carbon.
C = 0,07
Cr = 20,0
Ni = 9,50
Mn = 4,00
Mo = 1,00
Electrode suitable for welding of dissimilar steels between
Manganese steel and carbon steel. Much applied in layers
of pad for hard flooring. The deposit has a high resistance
to oxidation (up to 850 degrees Celsius), cavitation and
hardening.
C = 0,12
Si = 0,63
Mn = 1,50
Cr = 26,0
Ni = 21,0
Electrode for welding of refractory steels. Metal deposited
resists up to 1200 degrees Celsius, and may be used for
filling or Union of internal parts of furnaces and pipes
subjected to high temperature. Has high resistance to
corrosion and oxidation.
C = 0,10
Si = 0,75
Mn = 0,90
Cr = 29,0
Ni = 9,00
Electrode suitable for welding of dissimilar and difficult

exceptional resistance to cracking and excellent mechanical
resistance.
C = 0,03
Si = 0,82
Mn = 2,00
Cr = 23,0
Ni = 13,0
Electrode connected to Cr and Ni, suitable for welding of
dissimilar steels (AISI 304 with carbon steel) and plating
(coating) of carbon steels and low alloy steels. Also applied
in refractory steels because it resists oxidation at
temperatures up to 1050 degrees Celsius.
C = 0,08
Si = 0,80
Mn = 1,50
Cr = 23,0
Ni = 13,0
Mo = 2,40
Electrode connected to Cr, Ni and Mo, suitable for
connection of dissimilar steels. This austenitic-ferritic
structure hardens to cold, making this appropriate to arrays
manufacturing and mold making. Due to addition of Mo the
League, there will be an increase of mechanical resistance
and resistance to corrosion.

Locate cracks, and eliminate cutting electrode or
chamfer or graphite electrode. Redo your teeth with
electrode CR 818-B2. With the help of a template,
leave it to the last pass the hard CR 50 coating.
Locate the cracks and clean with Sander or cutting
electrode or chamfer. Apply the electrode of low alloy
steels in wide and short passes. Expect cool on every
pass.
Locate the cracks and clean with Sander or cutting
electrode or chamfer. Pre heat the gear with the aid of
electric resistance and thermal blanket. Apply the
electrode of low alloy steels in wide and short passes,
waiting for cool every pass. At the end of the weld
maintain thermal blanket until the total cooling of the
part. For steels 4350/1050 use CINOX 118 Mol-17.

Clean metal base. Give a narrow and long on the crest
of bagel with hard coating electrode, taking care not to
damage the screw diameter. Check out the clip and
give (swarming) with a finishing Sander.
Make an internal feedback of at least three teeth.
Apply hard coating electrode worn areas with long and
short passes. Check with feedback on each pass. Most
alternative CR50 hardness.
Apply the hard coating electrode around the contour of
the teeth. Apply one pass on the surface of the teeth.

Make a base with CR 60 passes by wide bathroom
type. Apply CR Z 65 with wide and short passes. In
the second pass give narrow cords shaped xxx
(chess). Be careful not to overheat the reeds because
the plates are thin and there is the danger of warping
and twisting.

CR 110-18M ou CINOX 106
Apply CR 110-18M in the wheel worn area, with short
passes and wide. The cords should be reassembled to
avoid failure in machining. Apply CINOX 106 allows
machining.
