DIM-L-1.4755
Welding wire DIM L-1.4755
Description:
DIM L-1.4755 SOFC
DIN EN: X1CrWNbTiLa22-2 Crofer 22H High performance material
Characteristics:
The solid wire electrode made of ferritic, stainless steel has been specially designed for use in solid oxide fuel cells (SOFC). The weld metal has a very good resistance against Laves-phase precipitations. At temperatures of up to 900° C (1652° F), a chromium-manganese oxide layer is formed which is thermodynamically very stable on the surface and has a high electrical conductivity. The low thermal expansion adapts very well to the typical ceramic
properties. Therefore it is possible to use high-temperature fuel cells from room temperature up to 900° C (1652° F).
Summary of typical features:
- Excellent corrosion resistance at high temperatures in anode and cathode gas
- Good durability
- Low chromium evaporation
- Easy to use
- Low thermal expansion coefficient
- Good electrical conductivity of the oxide layer
Materials:
Special Cr steels for high temperature fuel cells (SOFC)
