General Description

AS P-307 is a basic coated electrode. It gives a filler metal of the Cr-Ni-Mo type that is high (4.5%) in Mn content. Weld beads are highly resistant to impact, wearing and cracking due to heat effects. It gives a fully austenitic, nonmagnetic weld metal

Applications

AS P-307 is used for forming a buffer layer for hardfacing and joining of armour steel plates, steel welds that are low hardenable and work-hardening austenitic Mn steels. It can also be used for dissimilar weld joints of C-Mn steels with austenitic and ferritic stainless steels. 

There is no need to apply heat treatment to armour steel plates before or after the welding. Interpass temperature during welding should not exceed 120°C.
