309LSi

type 
Solid stainless steel welding wire for dissimilar welding
applications 
Buffer layers before hard facing, dissimilar joints between ferritic and austenitic steels and or difficult to weld steels.
Properties 

High mechanical properties and very good weldability due to a ingreased silicon content, suitable for operating temperatures up to 300°C.
