Alloy Alloy 2507<\/strong>, also known as\u00a0UNS S32750<\/strong><\/a><\/span> or super duplex 2507<\/strong>, is a stainless steel alloy designed to withstand particularly aggressive conditions. Due to its duplex microstructure (approximately 50 percent austenite and 50 percent ferrite), this material combines very high corrosion resistance<\/strong> with high mechanical properties<\/strong>, making it a strategic choice in critical industries such as offshore, marine, energy, and chemical industries.<\/section>\n

Chemical composition of Alloy 2507<\/h2>\n

The formula ofAlloy 2507<\/strong> was developed to provide superior performance both mechanically and chemically. Typical composition includes:<\/p>\n

    \n
  • Chromium (Cr)<\/strong>: 24-26%<\/li>\n
  • Nickel (Ni)<\/strong>: 6-8%<\/li>\n
  • Molybdenum (Mo)<\/strong>: 3-5%.<\/li>\n
  • Nitrogen (N)<\/strong>: 0.24-0.32%.<\/li>\n
  • Iron (Fe)<\/strong>: balanced<\/li>\n<\/ul>\n

    This combination ensures a high PREN index (>40), a parameter that measures resistance to pitting and cracking corrosion.<\/p>\n<\/section>\n
