'Hierro' and 'acero' are often used interchangeably. The advent of steel rolling mills in the 19th century ended the use of plate iron except in very specialized circumstances. I would go with 'steel'.

Buenas opciones, las ya ofrecidas. Pero creo que no es steel (acero), sino iron (hierro). Corríjanme mis colegas si me equivoco.
