Description：
An austenitic stainless steel electrode designed to weld 25Cr20Ni steels. The weld metal heat resistance scaling up to 1100-1150°C and does not contain any measureable ferrite. It can also be used to weld certain air hardening steels such as armour plate and joint stainless to unalloyed steels. Used to weld similar composition heat resistance stainless steels, high hardenability chromiums steels and dissimilar steels.
