Abstract

"CHAPA DE AçO IMERSA A QUENTE DE ALTA RESISTêNCIA à TRAçãO E MéTODO PARA PRODUZì-LA". Quanto à composição do aço, nesta invenção o teor de Si é regulado para uma faixa dada e Nb e Cu ou Ni, Mo são adicionados combinadamente, e um recozimento de recristalização é executado para formar uma camada de óxido interna logo abaixo da superfície de uma chapa de aço e um óxido de superfície formado simultaneamente na superfície da chapa de aço é removido por decapagem. Como resultado, a formação de óxidos de Si, Mn e similares é diminuída consideravelmente na superfície da chapa de aço em um aquecimento subseq³ente antes do revestimento porque a camada interna de óxidos acima age como uma barreira de difusão. Assim, de acordo com a invenção, podem ser obtidas chapas de aço imersas a quente de alta resistência à tração que tenham uma propriedade de revestimento consideravelmente excelente.
