Stainless Steel Electrodes

ES 308-15 Mo A5.4: E308 Mo-15 / EN 1600: E 20 9 3 B 2 2

Description

ES 308 Mo B IS a basic coated electrode. It gives a filler metal of the Cr-Ni-Mo type that is high (2.5%) in Mn content. Weld beads are highly resistant to sudden impact and cracking due to heat effect.

Applications

It is used for forming a buffer layer for hard facing and joining of armour steel plates, heat treatable steels, different type steels and for steels with poor weld ability.<br> There is no need to apply heat treatment to armour steel plates or after the welding. Inter pass temperature during welding should not exceed 120°C. It is also used to form a buffer layer for stress relief before hard facing applications.
