 Print Sheet


CLASSIFICATION: EC439 per AWS/ANSI A5.9, ASME SFA 5.9

Select FP 439Ti is a ferritic stainless steel, metal cored, composite electrode for the welding of 18% chromium steel, particularly on thin section aluminized material. Titanium is the stabilizing agent utilized to provide oxidation and corrosion resistance.

APPLICATIONS: This wire is an excellent choice for welding aluminized exhaust system components of 18& chromium. These typical components are fabricated from sheet stock and include manifolds, mufflers, catalytic converters and exhaust tubing.

DIAMETERS: .045", .052", 1/16"

SHIELDING GAS: 95-98% Ar/2-5% O2, 40-55 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Minimal spatter and literally no burn through on thin material.
  • Stable spray arc over a wide range of current and voltage settings.
  • Reduced stress corrosion cracking when welding over lubricants, oils and other hydrocarbons.
  • Better corrosion resistance at higher temperatures.
