All-State
Ni-Matrix® Electrode
for Fabrication and Build-up of Manganese Steels AC
or DC Reverse or Straight Polarity All
Position General
Characteristics All-State
Ni-Matrix® has a low hydrogen coating
and will deposit austenitic weld metal that is high in ductility
and strength. The welds provide excellent
resistance to heavy impact and compressive loads. The weld metal
on the surface will work harden; but
below the surface, it will remain tough and ductile. All-State Ni-Matrix®
has proven to
be superior in performance and less expensive than stainless steel electrodes
for most applications on manganese
steels. Deposits can be cut with oxygen/fuel torch. Typical
Applications Recommended
for use where the welds are subject to constant severe impact and heavy compressive
tools. Used to
attach wear plates, blades, teeth and other parts to heavy equipment. Other applications
are mill hammers, crusher
liners, dipper teeth and lips, dragline buckets, railroad switches and crusher
jaws. Qualities
Tensile strength
—up to 116,000 psi (81.58 kgs/mm2)
Hardness
—89
Brinell—as welded
—510
Brinell—work hardened Procedures
No special technique is required but
some general recommendations should be followed. Do not weld on base
metal that is not clean or sound. Be
sure that base metal has not been hardened. No preheat is necessary. Keep
base metal heat to a minimum by using
large electrodes, low amperage and short arc length.
