Roll Matrix® Machinable
Build-up and Underlay Electrode for Low Alloy and Abrasion Resistant Steels
AC or DC Reverse Polarity (Electrode
+) All Position General
Characteristics Completely
machinable deposit for heavy impact and compression on abrasion resistant, carbon
and low alloy steels.
Deposits have excellent toughness and resistance to deformation. They can be forged
and flame cut and will
respond to heat treatment. Typical
Applications Ideal
for tractor pads and rollers, sprockets, idlers, hammers, wobblers, excavators,
shafts, gear teeth, steel mill roll
necks and ends, and all carbon steel parts requiring build-up prior to hardsurfacing.
Qualities Tensile
strength —up
to 105,000 psi (73.84 kgs/mm2) Hardness
—25 to 30 Rockwell C
Procedures Clean
weld area. Use All-State® Chamfer Rod
to remove fatigued or damaged metal. Preheat is usually not
necessary but heavy sections may require
a preheat of 200°-300°F (93°-149°C). Hold a short to medium
arc length. Remove
all slag between passes. Use stringer or weave beads. Do not allow excessive heat
build-up. Allow
part to cool slowly.
