Postalloy® DuraChrome™ 2834-MCO

Postalloy® DuraChrome™ 2834-MCO is a specially formulated chromium carbide alloy developed to produce a superior high polish abrasion resistant deposit in service. The tough alloy matrix combination is designed for high abrasion and moderate impact. Heat resistant to 1000 °F (538 °C). Use on low carbon mild steel, manganese, stainless, and low alloy steels.

  • Good out of position capabilities
  • Fast freezing weld deposit
  • Very good weld bead tie-in
  • Ideal for dirty surfaces
  • Works well for sugar mill roll teeth (Picote)

Welding Parameters

Current Type: DC Electrode Positive , DC Electrode Negative

Volts Amps Diameter Stick Out
21-27 120-140 .045" (1.2mm) 3/8"-1/2" (10-12.7mm)
22-28 170-300 1/16" (1.6mm) 1"-1 1/4" (25-32mm)

Welding Procedure:

Out Of Position

Diameter: .045" (1.2mm); Amps: 80-130; Volts: 16-19; Stick-Out: 3/8"-5/8" (10-15.8mm)

Diameter: 1/16" (1.6mm);Amps: 100-140; Volts: 16-20; Stick-Out: 3/8"-5/8" (10-15.8mm)

When welding out of position, lower wire feed speed.
