Whether LR AH40 shipbuilding structural plate need preheating

Since it was established in 2000. Based on the domestic rich LR AH40 shipbuilding structural plate product resources and the great steel demand of the international market, our LR AH40 shipbuilding structural plate 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

ASTM A283 steel LR AH40 shipbuilding structural plate is a carbon steel plate used for general structural purposes. This steel has low strength and medium strength. It has two steel grades (C and D). For steel coils or unheated steel plates, additional stress relief tests should be carried out. Usually, inspections, inspections, and LR AH40 shipbuilding structural plate heat treatments should be carried out before leaving the factory after the coils are opened.

Shipbuilding steel plates have always been the key products of our company, and it is sold well in many countries and regions around the world. The thinnest certifiable thickness of our shipbuilding steel plates is up to 3mm. We cooperate with classification societies to certify the shipbuilding steel LR AH40 shipbuilding structural plate and issue EN10204 3.2 material test certificate. According to the certificate number, the customer can verify the source of the shipbuilding steel plates with the corresponding classification society near them.

The addition of Ca element in steel such as LR AH40 shipbuilding structural plate can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.

LR AH40 shipbuilding structural plate 2020 spot size: 16*1800*6000, 15*2500*10000, 25*2400*8200, 50, 25*2400*8200, 16*2000*10713, 25*2400*8200, 16*2270*11900, 15*2500*10000, 25*2400*8200, 28*2170*13000, 130*2200*7700, 100*1770*6650, 88*3440*9200, 12*2200*8000, 8*2200*5730, 16*2320*10000, 30*2400*9680 12*2200*8000, 16*1800*6000, 50*1820*10700, 130*2200*7700.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate LR AH40 shipbuilding structural plate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
