COLD-ROLLED STRIP FROM LOW-CARBON STEEL 08Ю FOR COLD FORMING Russian patent published in 2009 - IPC C21D7/00 C21D8/02 

Abstract RU 2360977 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to receiving of cold-rolled strips from low-carbon steel "08Ю" for following cold-pressing. Strip is implemented with thickness h = 0.6…2.5, mm, width B = 1000…1200, mm, surface roughness Ra=0.6…1.4, mcm, thickness difference of medium by width part of strip and its edges in one section in limits (0.018…0.022)•10-3•B, mm, strip wedging in one section h1-h2<0.015•10-3•B, mm, where h1 and h2 - thickness of opposite side edges of strip, mm.

EFFECT: it is improved following strips formability and increased yield at forming of rolled sheet of categories complex and extra complex total extension.
