Shipbuilding RINA FH40 high tensile steel plate steel plate refers to hot-rolled steel for the manufacture of ship structures produced in accordance with the requirements of the RINA FH40 high tensile steel plate construction society. Often used as a special steel ordering, scheduling, sales, a ship including ship plates, steel and so on.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium RINA FH40 high tensile steel plate carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some RINA FH40 high tensile steel plate alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
