Features and Benefits:
Blue Demon ER4130 Tig Wire is a low alloy, welding wire suited for welding very high strength low alloy steels as well as tool steels like AISI 4130, 4140, 4150 and 4340.
In some cases may be used to weld AISI 8620.
Also for joining steels of similar chemical composition, as well as for overlays where moderate hardness is required.
Normal preheat 200C. Inter-pass 430C.
After completion of welding a slow cool to prevent cracking. Final heat treatment will determine physical data.
