Abstract

Se revelan una chapa de acero y una chapa de acero galvanizada por inmersión en un bano caliente, con capacidad protectora contra la radiación electromagnética. La chapa de acero es preparada a partir de una composición que comprende C, N y S en una cantidad de 0,0150% en peso o menos, en total; Mn en una cantidad de 0,1 a 1% en peso; Si en una cantidad de 0,5% en peso, o menos; Al en una cantidad de 1,0% en peso, o menos; P en una cantidad de 0,06% en peso, o menos; estando el resto constituido por hierro y elementos inevitables, y muestra un límite de fluencia de 18 kg/mm2 o superior, y una elongación del 40%, o superior. La chapa de acero galvanizada por inmersión en un bano caliente, es preparada a partir de una composición que comprende C, N y S en una cantidad de 0,0150% en peso o menos, en total; Mn en una cantidad de 0,2 a 0,8% en peso; Al en una cantidad de 0,6% en peso, o menos; Si en una cantidad de 0,4% en peso, o menos; P en una cantidad de 0,06% en peso, o menos; con la condición de que la suma de Mn, Al, Si y P, sea aproximadamente 0,2 a 1,0% en peso; estando el resto constituido por hierro y elementos inevitables. Además de tener un elevado límite de fluencia, la chapa de acero galvanizada por inmersión en un bano caliente, resiste a la corrosión gracias al recubrimiento hecho de elemento resistente a la corrosión, sobre su superficie.A steel plate and a galvanized steel sheet are immersed in a hot bath, with protective capacity against electromagnetic radiation. The steel sheet is prepared from a composition comprising C, N and S in an amount of 0.0150% by weight or less, in total; Mn in an amount of 0.1 to 1% by weight; If in an amount of 0.5% by weight, or less; Al in an amount of 1.0% by weight or less; P in an amount of 0.06% by weight or less; the rest being made up of iron and unavoidable elements, and shows a yield limit of 18 kg / mm2 or higher, and an elongation of 40%, or higher. The galvanized steel sheet by immersion in a hot bath is prepared from a composition comprising C, N and S in an amount of 0.0150% by weight or less, in total; Mn in an amount of 0.2 to 0.8% by weight; Al in an amount of 0.6% by weight or less; If in an amount of 0.4% by weight, or less; P in an amount of 0.06% by weight or less; with the proviso that the sum of Mn, Al, Si and P, is approximately 0.2 to 1.0% by weight; being the rest constituted by iron and inevitable elements. In addition to having a high creep limit, the galvanized steel sheet by immersion in a hot bath resists corrosion thanks to the coating made of a corrosion-resistant element on its surface.
