FLUX CORED WIRE FOR WELDING MEDIUM-ALLOYED HIGH-STRENGTH STEELS Russian patent published in 2024 - IPC B23K35/368 

FIELD: various technological processes.

SUBSTANCE: invention can be used for welding structures from high-strength medium-alloyed steels for various purposes. Flux cored wire is made in the form of a shell from ferritic stainless steel filled with a charge. Wire contains components in the following ratio, wt.%: chrome 4.0–6.0, nickel 3.0–5.0, ferromolybdenum 3.0–4.6, nitrided chrome 2.4–3.3, sodium silicofluoride 0.5–2.0, manganese 5.3–7.4, copper 2.0–3.0, ferrosilicon 0.35–0.45, shell from ferritic stainless steel – the rest.

EFFECT: flux cored wire provides obtaining of high indices of ultimate resistance and yield strength of welded joint at increase of indices of relative elongation.
