Description |
|
63643 |
rutile-coated stick electrode on Cobalt base, core wire alloyed
UTP CELSIT 721 3,2 x 350 mm
Cobalt-based thermo shock resistant alloy for overlay applications |
|
|
APPLICATIONS |
|
Cladding valve seats, repairing machining tools. Repair of
damage due to erosion, high temperature and corrosion. Many applications in
the high pressure steam, oil and petrochemical. |
|
WEARstick Co 21 is used for crack-resistant hardfacings on
parts subject to a combination of impact, pressure, abrasion, corrosion and
high temperatures up to 900ºC, such as running and sealing faces on gas,
water, steam and acid fittings and pumps, valve seats and cones for
combustion engines, working parts in gas and power plants, hot-working tools
with changing thermal load. |
|
Excellent gliding characteristics, good polishability and
toughness, highly work-hardening, nonmagnetic, machinable with cutting tools. |
|
WEARstick Co 21 has excellent welding properties and a
homogenous, finely-rippled seam. |
|
Very easy slag removal. |
|
Hardness of the pure weld metal: 31 – 37 HRC |
|
Work-hardened: approx. 45 HRC |
| Hardness at 600 ºC: approx. 240 HB |
