Q460 steel plate has very high strength and is widely used in large ships, bridges, power station equipment, medium and high-pressure boilers, high-pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. The price of A514 grade E QT steel plate, Q460 steel plate is related to the specifications. Generally speaking, the thicker the thickness, the higher the price. And A514 grade E QT steel plate, Q460 steel plate price is also related to the market situation. When the market demand is in the peak season, the steel supply exceeds the demand, the price will rise. Otherwise, the price may be lowered. Finally, it is related to the order quantity. The larger the quantity, the more advantageous the price.
Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of A514 grade E QT steel plate capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the A514 grade E QT steel plate overall strength, competitiveness and anti risk ability of the company.
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the A514 grade E QT steel plate steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the A514 grade E QT steel plate weathering steel is purified and the content of inclusions is greatly reduced.
Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with A514 grade E QT steel plate, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.
Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
