All-State
Hard-Tuff 56® For
heavy impact and abrasion on carbon and manganese steels.
High deposition rate smooth arc.
AC or DC Straight or Reverse Polarity
General Characteristics
All-State Hard-Tuff 56®
electrode is designed to provide porosity free welds on all weldable grades of
carbon steel.
The weld deposit is also smooth, uniform and will give excellent service life
to new and worn parts. Can be
used with low voltage machines. Typical
Applications Gyratory
crusher parts, muller tires, conveyor bucket lips, roll crushers, impactors, hammermills
and most parts subjected
to heavy impact. Ideal for farm and shop applications. Qualities
Hardness on SAE 1020 Steel—54-56
Rockwell C. Deposits are non-machinable and cannot be heat treated. Both
stringer and weave beads may be employed.
Check cracks may appear when new weld cools. The cracks will not
change wear resistance, but will aid
in prevention of distortion. Two weld layers recommended.
Procedures On
carbon steels, build up to approximate desired shape with All-State Roll Matrix®,
on manganese steels, use with
All-State Ni-Matrix®. Apply Hard Tuff
56® to a maximum of 1/4" (6.4mm) or two
weld layers. NOTE:
When welding manganese steels, do not overheat base metal.
(600°F (316°C) Maximum).
