Postalloy®DuraChrome™ 2818-MCO
Postalloy® DuraChrome™ 2818-MCO is a chromium carbide hardfacing alloy that produces a controlled micro-structure of specially sized carbides in a very tough matrix. For applications involving high impact combined with abrasion. Weld metal is tougher than conventional chromium carbide alloys with fewer stress relieving check-cracks. Use on carbon, low alloy, and manganese steels
