Structure
Thermanit 625 PW is a Ni-based rutile flux cored wire for high-class joints of
high Mo-alloyed Ni-base alloys (e.g. Alloy 625 and Alloy 825) as well as stainless
steels with high Mo-contents (e.g. “6 Mo „ -steels). The wire is suitable for
creep and/or heat resistant and cryogenic materials, mixed joints and difficult
to weld low-alloyed steels. Furthermore it is applicable for pressure vessels
from – 196 °C up to + 550 °C. Avoid a temperature range between 600 and
850 °C due to the embrittlement of the material.
Further characteristics are the reliability against hot cracking, thermal shock,
stress corrosion cracking and pitting corrosion (PRE N 52), a low coefficient of
thermal expansion between c-steels and austenitic CrNi(Mo)-steels and a
completely austenitic non-corrosive structure.
The C-diffusion at high temperatures or heat treatments of non-similar joints
is inhibited. Welding in vertical-up position is possible.
