LH 981S
High strength basic electrode
Description & applications
Low hydrogen basic coated electrode with a deposit which has a high yield strength and is very tough - , particularly recommended for root passes on fine grain steels resistant to a tensile strength between 550 and 700 MPa (ex : rail of travelling crane...).
