METHOD OF PRODUCING ROLLED BLANKS FROM ALLOYED COLD-CHARGED MATERIALS Russian patent published in 1999 - IPC

Abstract RU 2124571 C1

FIELD: metallurgy, more specifically, production of rolled products of important application with high corrosion resistance. SUBSTANCE: method includes charging of mixture to steel melting unit with carbon-containing part in the form of pig iron containing the following ingredients, wt.%: C, 4.0-4.5; Si, 0.5-1.8; Mn, 0.3-1.0; Cr, 1.0-2.0; Ni, 0.3-0.8; Co, 0.01-0.02; P, 0.01-0.25; Fe, the balance. The method also involves melting of steel of definite composition, steel teeming, austenization, rolled product deformation in four stages and its final cooling. EFFECT: increased corrosion resistance of metal products. 3 cl
