| Description
and Applications |
| Hardtech
350 is a basic coated electrode designed to provide low |
| hydrogen
medium hard and tough deposits on mild and low alloyed steels |
| subjected
to medium compression al stresses and metal to metal friction |
| wear.
It is recommended also for joining parts subjected to heavy |
| solicitations,
weld metal, highly resistant to cracking, is machinable. |
| Applied
under inclined angle of 20ºC max, on rails MnCrV alloyed frogs, |
| truck
rollers, idlers, drive sprockets, heavy crushing |
| equipments,
power shovels gear wheels, roller shafts, caterpillar truck |
| components,
crane wheels, wobblers, rope pulleys. |
| Hardness
of the deposit depends on the number of passes and cooling |
| conditions. |
