S-700B.B

FIller Metal Breakdown

S-700B.B

S-700B.B is an electrode depositing weld metal of martensite which is harder than that of S-600B.B. This electrode, all weld metal of very hard martensite structure containing small quantity of austenite structure. Machining is impossible “as welded”. It is mostly suitable for soil abrasion.
