S690QL steel hardness fast delivery to Asia

Weathering steel for welding structure is added a small amount of alloy elements to the steel, such as steel, chromium, nickel, molybdenum, niobium, titanium, zirconium and vanadium, to form a protective layer on the surface of the metal substrate. Therefore, this improve the corrosion resistance and has good welding performance. Weathering steel for welding structure is mainly used in bridges, buildings and other structures. Our company can supply weathering steel plate, sheet, strip and sections, S690QL steel hardness with various shapes.

Since it was established in 2000. Based on the domestic rich S690QL steel hardness product resources and the great steel demand of the international market, our S690QL steel hardness 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

Try to use S690QL steel hardness high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the S690QL steel hardness temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, S690QL steel hardness, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
