| Description
and Applications |
| Rutile
coated stabilized austenitic electrode with stainless steel core wire, |
| for
welding of stabilized austenitic 18Cr/8Ni and 13%Cr steels type |
| stainless
steels. |
| Distinguished
by its outstanding welding characteristics such as excellent |
| out
of position weldability, good striking properties, stable
arc and no |
| spattering,
high hot cracking resistance, easy slag removal without |
| residues,
excellent resistance to sanitation during high temperature |
| service,
homogenous and finely rippled seam resistant to intergranular |
| corrosion
up to 400ºC. |
