Our company specializes in the production of duplex stainless steel ingots, seamless pipes, castings, and forgings. Duplex stainless steel has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with lowest alloy content has higher resistance to stress corrosion cracking than austenitic stainless steel, especially in environments with chloride ions. Stress corrosion is a prominent problem that cannot be solved in ordinary austenitic stainless steel. Application scope: petroleum, offshore oil, chemical industry, pharmaceutical machinery, aerospace, nuclear power, shipbuilding, high-pressure boilers, heat exchangers, pressure vessels, condensers, water conservancy, power industry, etc. Main steel grades include 2205, 310S, 316L, 2507, and various alloy castings. Weight ranges from 3 tons to 50 tons.
