In production and operation, the company always attaches great importance to product A588 Gr A high strength steel quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market A588 Gr A high strength steel. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.
SA517GrQ material is a high-strength quenched and tempered alloy steel plate, which belongs to the steel for offshore oil drilling racks. The upper limit of SA517GrQ steel plate thickness is 150mm, and the upper limit of rack steel is 177.8mm. BBN STEEL has opened up a new heat treatment process route for the 177.8mm thick offshore platform rack steel A517GrQ, and strives to improve the production capacity of this product.
The Performance requirements of low alloy structural steel, A588 Gr A high strength steel:(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.
Try to use A588 Gr A high strength steel 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 A588 Gr A high strength steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
Our A588 Gr A high strength steel, GB/T 1591-2008 Q460D plates are supplied with thickness up to 100mm.
