All-State Super 18-HI Electrode For
High or Low Heat and High Corrosion AC/DC
Reverse (+) All Position, Machinable General
Characteristics Thermal
shock resistance alloy for high and low temperature extremes and rapid changes
ranging from 1900°F to
–140° F (1050° C to –96° C). Superior corrosion resistance
and mechanical properties. Works well on small AC
machines.
Typical Applications
Use on clad steel, since it accepts
dilution exceptionally well. Joins nickel-to-steel. Excellent toughness and crack
resistivity. Suitable
for nickel-based alloy types Inconel 600, 625 and 800; and “Super” stainless
steels in injection molds,
receptacles for chemical and liquid gas industries, cracking installations and
heat exchangers. Qualities
