Refining of the Steels Significantly Improve the Quality

Abstract:

Steel alloyed by nickel, chromium and molybdenum reach according to normative standards (EN) yield point about 900 MPa and contraction about 25% after heat treatment. Authors of this paper noticeably increase the strength properties of that steel without changes in plastic properties with using of electroslug remelting refining technology (ESR). Subject of research are forgings of very large mass and dimensions. The forgings are used in special armament technology as (tank gun barrels). Very negative influence on mechanical properties of final product has content of nanodimensioned impurities.
