MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617060425 A) filed by Arcelormittal on May 12, 2026, for High Bendability Press-Hardened Steel Part And Method Of Manufacturing The Same.
Inventor includes Philippot, Clment International Bureau.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The invention deals with a high bendability press hardened steel part having a composition comprising, by weight percent: C : 0.05 - 0.14 %, Mn : 1.4 – 2.5 %, Si : 0.1 – 1.5 %, Al : 0.02 – 0.1 %, Cr : 0.01 – 1.0 %, B : 0.0005 - 0.004 %, Ti : 0.01 - 0.1 %, P = 0.020 %, S = 0.010 %, N = 0.02 % and comprising optionally one or more of the following elements, by weight percent: Ni = 0.4%, Mo = 0.40 %, Nb = 0.08 %, Ca = 0.1 %, the remainder of the composition being iron and unavoidable impurities resulting from the smelting. The press hardened steel part comprises a bulk having a microstructure comprising, in surface fraction, 85% or more of martensite the rest being bainite, an interdiffusion layer having a thickness thinter, a coating layer having a thickness thcoat and based on aluminium, the ratio thinter / (thinter + thcoat) being above or equal to 70%.
