Austenitic-ferritic duplex stainless steel is a type of steel that typically contains 5%-40% ferrite to improve the alloy's weldability, increase strength, and enhance stress corrosion resistance. For example, the high carbon and high chromium alloy steel with 28% chromium, 10% nickel, and 0.30% carbon has excellent resistance to sulfuric acid corrosion, making it suitable for manufacturing castings. Building upon this, controlled ferrite steel has higher strength and good stress corrosion resistance in sulfate environments, making it commonly used in the petroleum industry.
