Postalloy® DuraChrome™ PS164-MCG

A martensitic tool steel type hardfacing alloy with numerous tightly packed carbides for excellent abrasion resistance under high impact. Deposits are smooth and free of any slag. One layer deposits exhibit wear characteristics that you would expect from chromium carbide hardfacing products. An excellent choice for OEM and after market wear parts. Also an excellent wire for MIG Carbide. An excellent alloy for repair of chromium carbide overlay plate defects.
