FIELD: metallurgy, namely production of strip of low alloy steel.
SUBSTANCE: in order to make steel strip with thickness no more than 5 mm, cast strip of austenite structure is passed through rolling mill for reducing its thickness at least by 15%. Then strip is subjected to accelerated cooling in temperature range 850 - 450°C at cooling rate no less than 90°C/s for converting austenite to ferrite. Deformed strip has yield limit 450 - 700 MPa.
EFFECT: enlarged assortment of products.
