Use to weld 1/2 Cr-1/2 Mo,
1 Cr-1/2 Mo, 1-1/4 Cr-1/2
Mo steels for high-
temperature and corrosive
service and for Cr-Mo to
carbon-steel welds.
Lower carbon content
improves resistance to
cracking. Use where
postweld heat treatment is
not performed.
Use for 2-1/4 Cr-1 Mo steel
for high-temperature
high-pressure piping and
vessels. For all
Cr-Mo-to-carbon-steel joints.
Lower carbon content
improves resistance to
cracking. Use where
postweld heat treatment is
not performed.
Use to weld HSLA steels
and nickel steels up to
3-1/2%. Gives high strength
and good toughness down
to -100°F (-73°C).
High Mn and Si contents
reduce porosity. For single
and multipass welding of
carbon and low-alloy steels.
Use on S-bearing (free
machining) steel. Farm
implements, auto parts,
light-gauge steel,
AISI 4130, T-1.
High-strength, tough weld
metal for critical welds.
HY80, HY100 and
higher-strength steels,
structural applications for
service as low as -60°F
(-51°C).
