Description
Machinable - High Chromium Crack Resistant Hardfacing Alloy.

Postalloy® DuraChrome™ 2833-MCO is a non-cracking high chromium hardfacing alloy that offers good resistance to 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.
