LY-D256

符合

GB /T 984 EDMn-A-16 EQUIVALENT NORM: AWS A5.13 EFeMn-A

Description:

LY-D256 is a low hydrogen potassium type hardfacing electrode.Both AC and DC can be applied.Small current and narrow weld bead are recommended.Hammer or quench the weld metal when it is hot to avoid tendency of cracking when welding.Weld seam metal has the features of work hardening and abrasion-resistance.

用途:

It is used for hardfacing parts that are easy to be abraded when impacted,such as crusher,steel rails,bulldozer,etc.

ATTENTION:
a.Welding electrodes must be baked for 1 hour at the temperature of 250℃ before welding.
b.Before welding ,the hardfacing weld metal must be cleared impurities away,such as rust,oil,moisture etc.
c. . Before hardfacing,the abraded high Mn element steel parts must be eradictaed the fatigue layer or be dealt with by water impact or proceed back welding by Cr-Mn steel welding electrodes(e.g.LY D276).
d.When welding,there is big yellow fume,so a well-ventilated place is necessary during welding.Welding should be in windward position.
