HOT-DIP GALVANIZED ALUMINISED STEEL STRIP WITH POLYMER COATING, YIELD POINT OF NOT LESS THAN 500 MPA AND HIGH VALUE OF RELATIVE ELONGATION AND METHOD OF ITS MANUFACTURING Russian patent published in 2020 - IPC C22C38/02 C22C38/14 C22C38/04 C23C2/06 

Abstract RU 2736476 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to production of cold-rolled sheets, in particular, to production of hot-dip galvanized aluminised steel strip with polymer coating, having yield point of 500–590 MPa and value of relative elongation greater than 15 %, as well as to method of its production. Steel strip has the following chemical composition, wt %: C 0.07–0.15; Si 0.02–0.5; Mn 1.3–1.8; N ≤ 0.004; S ≤ 0.01; Ti ≤ 0.15; Nb ≤ 0.050; the rest is Fe and unavoidable impurities, wherein: (C+Mn/6) ≥ 0.3, Mn/S ≥ 150, 0.01 ≤ (Nb−0.22C−1.1N) ≤ 0.05 without Ti, Ti 0.5 ≤ Ti/C ≤ 1.5 in the absence of Nb, 0.04 ≤ (Ti+Nb) ≤ 0.2, where Ti and Nb are added together.

EFFECT: steel strip has good strength, viscosity and excellent anti-corrosion resistance.
