Postalloy® DuraChrome™ PS135-MCO

Postalloy® DuraChrome™PS135-MCO is a large diameter, high hardness multi-carbide hardfacing alloy

containing large volumes of Chromium and Niobium carbides uniformly throughout a tough alloy matrix. It is

recommended for applications involving severe abrasion or abrasion coupled with impact. Large diameter

wire is generally more alloy rich than smaller diameter wire.
