Abstract

PLACA DE AÇO COM BAIXA SENSIBILIDADE À TRINCA DE SOLDAGEM, E SEU MÉTODO DE FABRICAÇÃO. A presente invenção se refere a uma placa de aço com limite de elasticidade em um nível de 890 MPa e sensibilidade à rachadura de soldagem baixa e a um método de fabricação para a mesma. As porcentagens em peso dos componentes da mesma são: C: 0,06 a 0,13% em peso, Si: 0,05 a 0,70% em peso, Mn: 1,20 a 2,30% em peso, Mo: 0 a 0,25% em peso, Nb: 0,03 a 0,11% em peso, Ti: 0,002 a 0,050% em peso, Al: 0,02 a 0,15% em peso, e B: 0 a 0,0020% em peso, em que 2Si+3Mn+4Mo = 8,5, e outros são Fe e impurezas inevitáveis. O uso de tecnologias de laminação termomecânica controlada e resfriamento é benéfico para melhora de resistência, plasticidade e tenacidade de placa de aço. O limite de elasticidade da placa de aço é maior que 890 MPa, a resistência à tração é maior que 950 MPa, o trabalho de impacto Charpy Akv (-20°C) é maior que ou igual a 120 J, e o indicador de sensibilidade à rachadura de soldagem Pcm é menor ou igual a 0,25%.
