Medium and heavy plates refer to steel plates with a thickness of 4.5-25mm, those with a thickness of 25.0-100mm are called thick plates, and those with a thickness of more than 100mm are extra-thick plates. BBN steel can supply cutting and welding service for heavy plates and a36 ship steel product. Medium and heavy plates are mainly used in construction engineering, machinery manufacturing, vessel manufacturing, pressure vessels, shipbuilding, bridge construction, etc.
a36 ship steel is mainly used for shipbuilding. Corrosion resistance and high strength-to-weight ratio make this steel plate very suitable for the efficient manufacture of hulls, bulkheads, upper decks and hatch covers of tankers, bulk carriers, container ships and LNG carriers.
In general alloying theory, according to the affinity between a36 ship steel alloy steel and carbon, alloy elements can be divided into carbide forming elements and non carbide forming elements. Common alloy elements are as follows: non carbide forming elements: Ni, Co, A1, Si, etc. Carbide forming elements: Mn, Cr, Mo, W, V, Nb, Zr, Ti (arranged from weak to strong affinity with carbon). In addition, there are rare earth elements, which are recorded as Re.
