EN 14343 (EN 12072, G 18 8 Mn)

DESCRIPTION
The wire gives a strong, ductile and tough austenitic deposit which work-hardens from about 200HV to 450HV. Also compatible with cast iron in some applications. The addition of about 6% Mn gives good crack resistance in difficult highly restrained joints.

TYPICAL APPLICATIONS

• Joining, repair and build up of 13% Mn (Hadfield) steel castings combinations of mild, harden able or stainless steels with little or no preheat.
• Use for mixed welding where deposits have to be heat treated and for surfacing and buttering.
• The most versatile and economic solid wires for dissimilar welds.
