Description:

Low heat input, non-machinable cast iron welding electrode for economy welding and repair.

Basis of Alloys:

C, Si, Fe

Application & Descriptions:

R-50NM is the most economical cast iron low heat input welding electrode. Weld metal exhibits good strength and toughness and is non-machinable in nature. Weld deposits also offer good abrasion resistance.

It has good bonding strength even with difficult-to-weld cast iron, Nickel-free deposits. Suitable for sealing oil-soaked cast iron parts, reclamation of damaged castings, repair of foundry defects, welding and repair of oxidized cast iron furnace, and welding rusty, corroded, dirty, or greasy parts. Also suitable for joining cast iron to cast steels.

Re-Dry Condition:

Re-Dry the electrode at 150°C for 1 hour.
