COMPOSITE STEEL FOR ELECTROMAGNETIC WEAPON

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention refers to metallurgy field, particularly to composite steel for manufacturing of electromagnetic weapon. Steel contains, wt %: carbon 0.04 - 0.12; silicon 0.10 - 0.60; manganese 5.0 - 12.0; chromium 19.0 - 21.0; nickel 4.0 - 9.0; molybdenum 0.5 - 1.5; calcium 0.005 - 0.010; niobium 0.03 - 0.30; nitrogen 0.40 - 0.70; silicon dioxide 2.0 - 10.0; aluminium oxide 3.0 - 15.0; iron and unavoidable impurities - the rest. Silicon dioxide and aluminium oxide are in the form of particles with nanodispersibility. ^ EFFECT: receiving of steel which is non-magnetic allows increased electrical resistance at simultaneous keeping of rates of plasticity, viscosity and electromagnetic permeability. ^ 2 tbl, 2 ex
