Typical chemical composition of all-weld metal wt%
Typical mechanical properties of all weld metal
Size (mm) & recommended weld parameters AC OR DC+
● All deposited weld metal contains approximately 29%Cr-9%Ni elements with higher ferrite content than others.
● Higher Cr content in weld metal than others to get good oxidation and crack resistance
