YAWATA 680 (For Stainless Steel & Dissimilar Metals)
Clssification : AWS A 5.4 : E312-16, DIN 8556 : E 29 9 LR 26
Approvals : -
Application : Welding of austenitic-manganese steel, welding spring steel, tool steel and armour steel. Joining non-alloy and high alloy steels. Also suitable as a buffer layers in hardenable steel.
YAWATA 312-16 is a rutile type austenitic-ferritic electrode with a 25～30% ferrite content. The weld metal is extremely crack resistant and lends itself admirably to the welding of dissimilar and difficult to weld steels. It can be used for the welding of high nickel alloys without becoming fully austenitic due to nickel pick-up.
