Since it was established in 2000. Based on the domestic rich military grade ABS AH36 ship steel product resources and the great steel demand of the international market, our military grade ABS AH36 ship steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
Corrosion-resistant steel plate significantly improves the corrosion resistance of structural parts and prolongs the service life of structural parts. It can be used to make various structural parts that work in atmospheric environments and corrosive gases and liquids. Plate military grade ABS AH36 ship steel delivery status: According to performance and user needs, steel plates can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering.
Compared with military grade ABS AH36 ship steel, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for military grade ABS AH36 ship steel pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common military grade ABS AH36 ship steel carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
Chemical composition differences between the military grade ABS AH36 ship steel, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
