Description: AFM E11018M was originally designed for military applications such as welding HY80 and HY100 type steels. To achieve desired weld-metal properties and soundness, AFM E11018M has small alloy additons (especially some Ni) and require careful control of moisture in the electrode covering and from other sources of hydrogen.
Applications: AFM E11018M is used to weld all forms of T-1 steel. It can also be used where high-strength welds with excellent low temperature impact properties are desired.
