METHOD OF PRODUCTION OF METAL FABRIC OUT OF STEEL Russian patent published in 2008 - IPC C21D8/02 C22C38/04 

FIELD: metallurgy.

SUBSTANCE: invention refers to production of steel sheets or steel strip. To achieve high yield strength, isotropic deformability and plasticity at low temperatures the method consists in production of a slab out of steel containing, mas.%: C: <1.00, Mn: 7.00-30.00, Al: 1.00-10.00, Si: >2.50-8.00, Al+Si >3.50-12.00, B: <0.01, Ni: < 8.00, Cu: <3.00, N: <0.60, Nb: 0.30, Ti <0.30, V: <0.30, P: <0.01, iron an unavoidable impurities - the rest; the method further implies heating of the slab to at minimum of 1100°C and hot rolling, finishing temperature of which is minimum 800°C, then winding of a hot rolled strip at a temperature from 450 to 700°C, then cold rolling of a hot rolled strip with a degree of deformation from 30 to 75% into a cold rolled sheet, recrystallisation annealing at a temperature from 600 to 1100°C and cold deformation with a degree of deformation from 2.5 to 25%.

EFFECT: facilitating of high yield strength, isotropic deformability and plasticity at low temperatures.
