LR DH36 watercraft structural steel,The method of distinguishing manganese plate from common carbon steel plate, is as follows:
(1) Check the spray label
Whether it is manganese plate or common carbon steel plate, it has its own factory spray mark, just check it;
(2)Listen to the cutting sound
The cutting sound of manganese plate is relatively clear and crisp, while that of common carbon steel plate is not clear and crisp, and the manganese plate will fall off as soon as it is cut;
(3) Look at the polishing sparks
Look at the amount of sparks on the surface during polishing. The more sparks and forks are manganese plates, and the lesser ones are common carbon steel plates;
(4) Check the material certificate
Generally, the material certificate will clearly indicate what material it is, just check it.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they LR DH36 watercraft structural steel work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

LR DH36 watercraft structural steel,The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
