PROWELD 312L STAINLESS STEEL Rods (Weldall 312)



312L Stainless steel welding rods are specially designed to weld metals of unknown qualities, often known as "Weld Alls"



Weld mild steel to stainless steel etc, ideal for welding dissimilar metals



2.5mm x 1.0Kg 312


Part code: PROWELD 312

DESCRIPTION :



SS-312 is a lime titanic electrode with 29Cr-9Ni% chemical composition containing large content of ferrite which made it good crack resistance.


It is suitable for dissimilar-metal joint and hardenable steels, steel armour and generally hard to weld steels.

APPLICATIONS :



Typical applications include marine, re-conditioning and refurbishment industries.

NOTE ON USAGE :



1. Rebake the electrodes at 250 ~ 300°C for 1 hour and keep it at 100 ~ 150°C prior to use.


2. Use stainless steel wire brush for cleaning of slags


3. Follow the recommended welding parameters to achieve good sound welds


4. Use lower current for dissimilar-metal joint.
