Postalloy® DuraChrome™
Postalloy® DuraChrome™ 2817-FCO is a flux-cored, open-arc hardfacing wire that provides a weld deposit of finely dispersed chromium carbides in a super tough austenitic matrix. Use for very high impact applications combined with abrasion resistance. Designed for carbon, low alloy and manganese steels. DuraChrome™ 2817-FCO develops a light cross-checking pattern which allows it to be applied in multiple layers.
