Seawater desalination, Marine chemical special duplex stainless steel, high molybdenum super austenitic stainless steel, corrosion resistant alloy for deep-sea gathering and transportation system, precipitation hardening type stainless steel, deep-sea drilling USES high grade and high nitrogen austenitic stainless steel and other materials research and development, production and application technology.
Key technology for manufacturing high performance corrosion-resistant steel. The corrosion mechanism, service behavior and evaluation methods of iron and steel materials under different corrosion environments (Marine corrosion, acidic environment, oil and gas corrosion, atmospheric corrosion, wear corrosion, etc.) were studied. Based on the material design method of the whole life cycle concept of the product, the corrosion resistant steel alloy composition design, smelting, continuous casting, rolling and cooling control, welding, mechanical processing and other technologies with different corrosion mechanisms are developed to form the corrosion resistant steel material system with our own intellectual property rights.
