Ordinary medium and thick steel plate RINA DH32 watertight bulkhead steel is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the RINA DH32 watertight bulkhead steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After RINA DH32 watertight bulkhead steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
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 RINA DH32 watertight bulkhead steel, 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.
