AK-ER307Si
Standard:
EN ISO 14343-A:G/W 18 8 Mn
AWS A5.9 ER307Si
Description: The welding wire is 21%Cr-9%Ni-6%Mn pure austenitic stainless steel wire. Due to the high content of Mn,
the crack sensitivity is low, and the fluidity of molten iron is good due to the additionof Si, the welding arc is stable, and
the molding is more beautiful. Can be welded in all positions..
Application: It is used for welding of non-magnetic, high-manganese steel and hardening corrosion resistant steel. It is
often used in nuclear submarines, bulletproof steel plates and other special occasions that require non-magnetic
properties. It can also be used for welding of dissimilar steels that are difficult to weld and easy to crack.
