Postalloy® DuraChrome™ 2833-MCO
Machinable - High Chromium Crack Resistant Hardfacing Alloy.
Postalloy® DuraChrome™ 2833-MCO is a non-cracking high chromium hardfacing alloy that offers good resistance to abrasion, corrosion, heat and galling and can be applied in multiple layers crack-free with proper welding procedures. Deposits are machinable with carbide tools. It is recommended for parts where a low coefficient of friction is desirable and where cross-checking is undesirable. Deposits will polish in service and are heat resistant to 1100 °F (593 °C). Use on low carbon mild steel, manganese, stainless, and low alloy steels.
