CATEGORY

TYPE

Filler metal for welding stabilized stainless austenitic steels that are exposed to working temperatures up to 400°C

APPLICATIONS

For welding stainless austenitic steels that are exposed to working temperatures up to 400°C.

PROPERTIES

The weld deposit is scale-resistant up to approx. 800°C in normal atmosphere and oxidizing gases. The weld deposit is capable of taking a high polish.

Structure: Austenite with delta ferrite
