Ship plate is a kind of steel plate used in shipbuilding, including thin plates and medium-thick plates. The China Classification Society rules divide steel plates into "ABDE" four quality levels, namely CCSA, CCSB, CCSD, and CCSE. There are many main materials for ship plates, such as BV DH36 hull shipbuilding plate, stainless steel, galvanized steel, shipbuilding steel plates, wooden ship plates, etc. Each material is used in different places. Generally, those large cargo ships at sea use stainless steel plates. Otherwise, if the ship plates rust, it will not only pollute the sea but also affect the ship itself.
The BV DH36 hull shipbuilding plate prices in the dominant market today is mainly stable. Regarding the transaction situation, some BV DH36 hull shipbuilding plate merchants reported that the current demand is poor, coupled with the shortage of resources in some areas, the overall transaction is not satisfied. For the market outlook, under the support of relatively high costs, high prices are supported, but the BV DH36 hull shipbuilding plate price increase momentum is insufficient due to poor demand. On the whole, it is expected that the BV DH36 hull shipbuilding plate market prices will remain consolidated tomorrow.
The main applications of normalizing are as follows:① For low carbon steel, BV DH36 hull shipbuilding plate. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
The steel grades BV DH36 hull shipbuilding plate of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of BV DH36 hull shipbuilding plate steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.
