Since it was established in 2000. Based on the domestic rich A514 Gr B QT steel plate product resources and the great steel demand of the international market, our A514 Gr B QT steel 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
Manganese steel vs carbon plate Manganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and A514 Gr B QT steel plate is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common.
Weather-resistant steel plate refers to steel plate that is resistant to weathering and corrosion. A514 Gr B QT steel plate, Weather-resistant steel plate can adapt well to the environment and is widely used in construction, bridges, roads and other fields with outstanding performance characteristics. One of the outstanding advantages of weather-resistant steel plate is its ability to adapt to a variety of different environments, whether it is in severe cold areas or tropical areas. The weather-resistant steel plate can better maintain its characteristics in various complex environment.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, A514 Gr B QT steel plate included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The A514 Gr B QT steel plate, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
