T Z 16 8 2 R M 3 (C3)
E16-8-2T0-1 / E16-8-2T0-4
|
Welding of stainless steels that operate at temperatures up to about 800°C. The deposit has excellent hot ductility and offers good resistance to weld cracking even under high restraint conditions. The very carefully balanced weld metal composition - Ferrite Number not higher than 5 FN - combines resistance to creep, oxidation and general corrosion. |
