LOW DENSITY HIGH STRENGTH STEEL AND METHOD FOR PRODUCING SAID STEEL
摘要:
The present invention relates to a low density high strength steel sheet comprising 0.15% to 0.25% C, 2.5% to 4% Mn, 0.02% or less P, 0. 015% or less S, 6% to 9% Al and 0.01% or less N, the balance being iron and inevitable impurities, wherein 1.7•(Mn-Al) + 52.7•C is at least 3 and at most 4.5 and to a method of producing said low density and high strength steel sheet.
