When to paint heavy steel sheet S690QL

Advantages of JIS G3101 SS400: Compared with other heavy steel sheet S690QL steel standards, the steel made of SS400 carbon steel is popular because of its proper tensile strength and toughness, good plasticity, welding performance and processing performance. The thickness of the heavy steel sheet S690QL steel plate ranges from steel plate to super thick steel plate.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, heavy steel sheet S690QL seamless steel pipes for ships and petroleum cracking heavy steel sheet S690QL steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many heavy steel sheet S690QL products have been exported to the Middle East, India, Southeast Asia and Europe and America.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to heavy steel sheet S690QL full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our heavy steel sheet S690QL steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.

The characteristic of niobium in heavy steel sheet S690QL etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
