Description

THE BEST "OUT OF POSITION" CHROMIUM CARBIDE HARDFACING ALLOY!!
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)
