Our company specializes in the production of duplex stainless steel ingot, seamless steel tubes, castings, forgings, Duplex stainless steel has excellent resistance to the ability to stress corrosion cracking, even the lowest-containing duplex stainless steel alloy also has a higher resistance than the austenitic stainless steel stress corrosion cracking capacity, particularly chlorine ions in the environment. Stress corrosion is a common austenitic stainless outstanding problems difficult to solve. Scope: oil, sea oil, chemical, pharmaceutical machinery, aerospace, nuclear power, shipbuilding, high-pressure boilers, heat exchangers, pressure vessels, condensers, water conservancy, electricity and other industries. Major steel 2101/2205/2304/2507.
