FIELD: metallurgy, namely manufacture of cast trip with enhanced limit yield.
SUBSTANCE: method comprises steps of continuously casting melt steel with concentration of residual impurities selected from group including copper, nickel, chrome, molybdenum, tin no more than 2.0 mass% depending upon microstructure of ready strip; cooling strip in order to convert austenite to ferrite in temperature range beginning from 850°C till 400°C.
EFFECT: strip cast by such method features increased limit yield.
