All-State®
No. 4-60* Premium
Electrode for Welding Heavy Sections of Cast Iron and Ductile Iron
AC or DC Reverse Polarity (Electrode
+ ) All Position General
Characteristics All-State®
No. 4-60 is a superior machinable electrode which gives maximum strength and ductility
on heavy sections
of cast iron. Due to its iron content it is excellent for welding ferrous metals
which are high in phosphorus content
and ductile iron. It can also be used to join these cast irons to steels.
Typical Applications
Recommended for general maintenance
welding where high strength and ductility are required and yet, deposits
must be machinable. Commonly used on
heavy machine bases, equipment parts, cylinder heads and blocks.
Qualities Tensile
strength—up to 80,000 psi (56.26 kgs/mm2)
Yield strength—up to 60,000 psi
(42.19 kgs/mm2) Elongation
in 2"—4 to 12% Hardness—200
to 300 BrineIl Deposit—magnetic
Color match—good
Procedures Preheating
to 600°F (316°C) is recommended to decrease stresses and increase tensile
strength and ductility. Removing
all foreign material by grinding or other means and then searing the iron with
a highly oxidizing torch flame
will help to eliminate porosity. When welding cast iron to steels, the procedure
should be the same as if two pieces
of cast iron are being joined together.
