The marine industry constantly demands materials that are both durable and reliable, capable of enduring the harshest of oceanic conditions. Among the leading choices for such applications is the DNV F460 marine steel plates, which are renowned for their excellent chemical composition, mechanical properties, and heat treatment characteristics.
Quenching and tempering shipbuilding steel plate DNV F460 is a higher steel grade among shipbuilding steel.Heat treatment mark would be appear as QT on our each steel plate as steel mark.The low temperature impacting test for these extra high tension steel plate shall be under minus 60 centigrade.
