Supply the element of hardox 400 grade

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 element of HARDOX 400, Q460 steel plate is related to the specifications. Generally speaking, the thicker the thickness, the higher the price. And element of HARDOX 400, 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.

The Performance requirements of low alloy structural steel, element of HARDOX 400:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

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 element of HARDOX 400 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 element of HARDOX 400 weathering steel is purified and the content of inclusions is greatly reduced.
