Basis OF Alloys : C, Si, Fe
Basis OF Alloys : C, Si, Fe
Application & Descriptions :
R-50NM is most economical cast iron low heat input welding electrode. Weld metal exhibits good strength and toughness and non-machinable in naturel. Weld deposits also offer good abrasion resistance. It has good bonding sterenght even with difficult to weld cast iron, Nickel free deposits, Suitable for sealing oil-soaked cast iron parts, for reclamation of damaged casting, repair of foundry defects, welding and repair of oxidized cast iron furnace, also suitable for welding rusty, corroded, dirty, greasy parts. Joining cast iron to cast steels.
RE-DRY CONDITION :
Re-Dry the electrode at 150°C for 1 hour
