Reverse Polarity Electrode All-State®
Hot Work Electrodes are recommended for welding damaged or worn hot working punches,headers,
trimmers, die
casting dies, cutting dies and shear knives in hot work operation, mandrels, piercers,
and ejecting rods.
Also used for composite fabrication of units requiring hot work steel of nickel-chrome
deposits. Properties
of Weld Metal Sound,
porous-free deposits have excellent hot work air hardening characteristics. Excellent
strength, toughness and
wear resistance at high temperatures. Withstand alternate heating and cooling
without checking, and will not scale
excessively. “As-Welded” hardness is approximately 52-55 Rc; can be
annealed or reheat-treated, drawn or tempered.
Use on base metals of AISI Types H-10, H-11, H-12 and H-13.
Heat Treatment
Anneal 1500°-1600°F (816°-871°C).
Harden 1750°-1850°F (954°-1010°C). Quench in oil. Harden 1800°-1900°F
(982°-1038°C).
Quench in air. Draw 900°-1200°F (482°-649°C). Cool in still
air. Procedure
Follow recommended welding procedure
on pages 2 and 3 carefully, especially preheating. With composite
fabrication of die unit, preheat to
500°F (260°C). To repair existing die units, preheat to 900°F (482°C)
and do not drop
below 700°F (371°C) during welding. Postheating
or Tempering Temper
to desired hardness or toughness to withstand condition to which unit will be
subjected. Diameters

(2.4mm)—60-90 1/8"
(3.2mm)—75-125 5/32"
(4.0mm)—100-150
