ALL-STATE®
4130-T For Low
Alloy Steel General
Characteristics All-State®
4130-T deposits have high tensile strength, and good elongation. The deposits
can be flame hardened. In
the annealed state, All-State® 4130-T
is machinable. Typical
Applications For
repairing medium carbon steels and high carbon steels where complete heat treatment
is desired. Such steels as
S.A.E. 4130, 4140, 4330, 4340, 8620 and 8630 all respond well to All-State®
4130-T. Qualities
Alloy type
- flame hardening
Hardness
- Rockwell “C” scale 36-38*
Tensile strength
-
138,000 psi to 163,000 psi* Procedure
Remove all foreign matter. Base metal
should be clean and dry. Thoriated Tungsten electrode used with
direct current, straight polarity (electrode
negative) and welding grade Argon gas should be used. Amperage is
determined by electrode diameter, base
metal thickness, and inert gas selected. Preheat and postheat will be
dictated by base metal chemistry, type
of weld and size of weld deposit. A 400°F (204°C) to 600°F (316°C)
interpass temperature
is suggested for SAE 4130 base metal. Sizes
1/16" (1.6 mm) x 36" (900 mm)
3/32" (2.4 mm) x 36" (900 mm)
