Abstract

"MéTODOS DE PRODUçãO DE MEMBRO ESTRUTURAL DE AçO DE ELEVADA RESISTêNCIA". Revela-se método de produção de membros estruturais de aço de elevada resistência que proporciona uma peça em bruto laminada de aço de elevada resistência tendo uma microestrutura de ferrite-perlite e propriedades mecânicas de elevada resistência e modelando a frio a peça em bruto por laminação ou semelhante, de modo a prover um membro estrutural com a seção reta geométrica pretendida, ao mesmo tempo que a resistência mecânica do membro estrutural permanece substancialmente a mesma ou maior do que a peça em bruto laminada."METHODS OF PRODUCTION OF STRUCTURAL MEMBER OF HIGH RESISTANCE STEEL". A method of producing high-strength steel structural members is revealed, which provides a laminated high-strength steel blank having a microstructure of ferrite-perlite and high-strength mechanical properties and cold forming the blank by rolling or similar, in order to provide a structural member with the desired geometric straight section, while the mechanical strength of the structural member remains substantially the same or greater than the laminated blank.
