FIELD: metallurgy; production of important rolled stock for oil-well tubing of increased service life. ^ SUBSTANCE: proposed method includes making steel of definite chemical composition in electric furnace, tapping metal from furnace into ladle, treatment of metal in ladle and teeming steel into ingot molds. Alloying with molybdenum is performed by introducing molybdenum-containing materials into furnace in making steel. After teeming, ingots are rolled, cooled and heated for rolling in preset temperature range and are subjected to preliminary and final deformation; process is completed by final cooling of rolled blanks to surrounding temperature. ^ EFFECT: improved strength characteristics and cold resistance of metal; enhanced reliability of metal products. ^ 1 ex
