Our company's A514 Gr P QT steel plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the A514 Gr P QT steel plate utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
ASTM A242, A514 Gr P QT steel plate used in marine and humid environments, is a high-strength, corrosion-resistant alloy with a yield strength of 42,000 to 50,000 psi and an allowable bending stress of 25,200 to 30,000 psi.
The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate A514 Gr P QT steel plate should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.
The addition of Ca element in steel such as A514 Gr P QT steel 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.
