Postalloy® DuraHard™ PS135-MCO
Postalloy® DuraHard™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.
