The rolling process of A131 AH40 offshore platform steel

With the development of China's A131 AH40 offshore platform steel market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of A131 AH40 offshore platform steel products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

ASTM A242, A131 AH40 offshore platform steel used in marine and humid environments, is a high-strength, corrosion-resistant alloy with a yield strength of 42,000 to 50,000 psi and an allowable bending stress of 25,200 to 30,000 psi.

Weather-resistant steel plate has excellent hot-rolled steel plate with resistance to sulfuric acid dew point corrosion. Its superior sulfuric acid dew point corrosion resistance and very high cost performance are the best materials A131 AH40 offshore platform steel that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). ND steel has great economic significance and is in line with today's high efficiency, long life and energy saving.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, A131 AH40 offshore platform steel Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach A131 AH40 offshore platform steel 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual A131 AH40 offshore platform steel production capacity: 3.5 million tons."
