All-State®
No. 252* Electrode
for Welding Alloy Steels AC
or DC Reverse Polarity (Electrode +) All Position General
Characteristics All-State®
No. 252 is used for welding of steels where corrosion, elevated temperatures,
and weld metal dilution present
a problem to the weld deposit. The higher alloy content of this electrode helps
to offset the dilution of the weld
metal when being fused to high alloy steels. Typical
Applications Welding
310 and 314 stainless steels subjected to corrosion and elevated temperatures
up to 2150°F (1177°C) as well
as dissimilar steels and stainless steels of unknown analysis. Use for armor steels,
AISI 410, 430, and 502 steels.
Ideal for attachments in material transfer applications of AR (Abrasion Resistant)
steels. Qualities
Tensile strength
—up to 95,000 psi (66.81 kgs/mm2)
Yield strength
—up to 65,000 psi (45.71 kgs/mm2)
Elongation in 2"
—35 to 45%
Hardness
—Rockwell
B85 Deposit
—nonmagnetic
Procedures Clean
weld area. Preheating 300°-500°F (149°-260°C) will minimize
cracking. Use stringer beads; do not weave. A medium
to short arc should be maintained and slag removed between passes.
