WELDING WIRE WITH HIGH NITROGEN CONTENT Russian patent published in 2022 - IPC B23K35/30 C22C38/58 

FIELD: technological processes.

SUBSTANCE: invention can be used for manual welding in protective gases of parts and structures from non-magnetic high-strength austenitic steels with high concentrations of nitrogen, for example, in oil and gas, shipbuilding or machine building industries. Welding wire contains components in the following ratio, wt.%: carbon 0.04–0.08, silicon not more than 1.0, manganese 14.0–16.0, chromium 19.0–23.0, nickel 6.0–9.0, molybdenum 0.5–1.5, vanadium 0.10–0.50, nitrogen 0.45–0.65, cerium 0.05–0.2, lanthanum 0.03–0.1, sulfur 0.005–0.010, phosphorus 0.010–0.015, iron — the rest, note here that total content of cerium and lanthanum should not exceed 0.25 wt.%.

EFFECT: obtaining non-magnetic weld metal and improving mechanical and corrosion properties of the welded joint.
