SELF GAS SHIELDING FLUX AND METAL CORED WIRE DEPOSITING AN AUSTENITIC 14Mn-ALLOY WITH EXCELLENT WORK HARDENING CHARACTERISTICS
FC-14MN
CLASSIFICATION
DIN 8555 MF7-200-GP
PRODUCT DESCRIPTION
A tight seamed roll-drawn tubular wire containing an evenly distributed mixture of alloying elements, deoxidants and chemically basic minerals. The minerals dissociate during welding to provide a full protective selfshielding gas which eliminates the need for an external separate shielding gas.
WELDING FEATURES OF THE ELECTRODE
Suitable for use on DC+ only, the strong forcefull arc is readily controllable and the high silicon content of the alloy lowers the surface tension of the molten weld pool, thus allowing ease of weaving and thus minimal dilution. Weld beads are bright and smooth and free from porosity. The slag volume is minimal and metal recovery is about 90% with respect to weight of the consumable
APPLICATIONS AND MATERIALS TO BE WELDED
This multi purpose alloy may be used to weld 14% manganese austenitic steels or to build up worn areas on such steels or to surface C-Mn steels with a 14% Mn deposit. The weld metal as deposited is soft and ductile but work hardens rapidly under impact loading or frictional pressure to provide a deposit resistant to wear by friction or abrasion. Ideal for railtracks, crossings, crusher rolls, bucket teeth and similar.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 120ºC for 1 hour.
