IRON-MANGANESE ALLOY WITH IMPROVED WELDABILITY Russian patent published in 2022 - IPC C22C38/04 C22C38/40 C21D8/02 C21D8/06 

FIELD: metal alloys.

SUBSTANCE: invention relates to a ferromanganese alloy, which can be used for the manufacture of parts and welded assemblies operating under varying temperatures. The alloy contains, wt. %: 25.0 ≤ Mn ≤ 32.0, 7.0 ≤ Cr ≤ 14.0, 0 ≤ Ni ≤ 2.5, 0.05 ≤ N ≤ 0.30, 0.1 ≤ Si ≤ 0.5, optionally 0.010 ≤ rare earth elements ≤ 0.14, the rest is iron and residual elements obtained as a result of manufacture.

EFFECT: invention is aimed at developing an alloy having high dimensional stability under the influence of temperature changes.
