Resumo
O trabalho tem como objetivo listar os principais desafios no desenvolvimento de aços para utilização em dutos resistentes ao serviço ácido na exploração e transporte de petróleo e gás. As principais etapas no processo de produção desde a aciaria até a produção das chapas são analisadas criticamente, e discutidos a influência da composição química e os parâmetros de processo nas propriedades mecânicas e de resistência a corrosão. Finalmente, é apresentado um quadro de tendências futuras na aplicação de graus API resistentes ao serviço ácido.

Abstract
The main challenges in the development of pipeline steels for sour service pipelines are briefly analyzed in the present work. The main production steps from steelmaking to plate rolling are reviewed and the influence of the chemical composition and processing parameters are correlated with the final mechanical properties and the resistance to hydrogen-induced cracking. Finally, a brief scenario is shown with future trends on the application of pipeline steels for sour service.
