Information of Product
E 731
Covered electrode for Wear Resisting Hard Surfacing Applications
Heavy Rutile Covering
Standards: - -
DIN 8555 E 10 - UM - 65 GRZ
AWS/ASME SFA-5.13 E Fe Cr - A2
Application and Properties:

Heavy coated, high recovery (235%) hardfacing electrode, depositing evenly distributed Cr, B carbides in austenitic stainless steel matrix. Suitable for hardfacing of parts subjected to heavy abrasion with moderate impact. Required hardness and abrasion resistance can be obtained in the first layer even on low alloy steels. The hardfacing layers have a very smooth surface and machinable only by grinding. Suitable to use in excavator teeth, leading edges of excavator buckets, mixer blades, gravel pumps, conveyor worn-screws, conveyor belts. Possible to use with both DC and AC.
