RA hull construction steel, Shipbuilding steel plate refers to hot-rolled steel for the manufacture of ship structures produced in accordance with the requirements of the RA hull construction steel construction society. Often used as a special steel ordering, scheduling, sales, a ship including ship plates, steel and so on.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched RA hull construction steel increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of RA hull construction steel during tempering, while tempering determines the performance and life of the workpiece.
Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, RA hull construction steel. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.
