Why some clients require to add some Boron into en 10025-6 S690QL equivalent ASTM

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 en 10025-6 S690QL equivalent ASTM, Q460 steel plate is related to the specifications. Generally speaking, the thicker the thickness, the higher the price. And en 10025-6 S690QL equivalent ASTM, 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 basic principle of en 10025-6 S690QL equivalent ASTM, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

en 10025-6 S690QL equivalent ASTM, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

Recently, the price of en 10025-6 S690QL equivalent ASTM raw materials has been strong, the mainstream steel mills have raised the price, and the cost of taking goods by en 10025-6 S690QL equivalent ASTM merchants has risen. In addition, macro capital will still have a disturbance to the market, and the current wait-and-see sentiment of downstream and middlemen is strong. On the whole, the steel market is intertwined with many spaces, and the supply and demand fundamentals are generally in a weak balance pattern. High inventory suppresses the price of en 10025-6 S690QL equivalent ASTM steel, and high cost supports the price of en 10025-6 S690QL equivalent ASTM steel, while macro capital also disturbs the market from time to time. In the short term, the market wait-and-see sentiment is strong, en 10025-6 S690QL equivalent ASTM steel prices or continue to fluctuate, the range of rise and fall are limited.
