Can someone recommend a filler material for welding AISI 430 to AISI 1020?
Confirm to permanently remove your answer!
First of all, AISI 430 is none hardening erratic stainless - primarily due to low 0.12% Carbon.
AISI 1020 is low carbon structural steel, equivalent to say an S335J2H (a European number).
Now, you can use E/ER 308 electrode for filler material.
Will check my cook books and add more later.
