Classification of Duplex Stainless Steel Sheets

Duplex stainless steels are classified according to their chemical composition and can be classified into four types: Cr18 kind, Cr23 (excluding Mo) kind, Cr22 type, and Cr25 type. For the Cr25 kind of duplex stainless steel, it can be divided into form and super duplex stainless steel. Among these, the Cr22 kind and Cr25 types are utilized. The specific grades are 3RE60 (Cr18 type ), SAF2304 (Cr23 type), SAF2507 (Cr22 type ), and SAF2507 (Cr25 type).

  • Cr18 Duplex Stainless Steel: Its chemical composition contains 18% chromium and about 5% to 8% nickel, as well as small amounts of molybdenum and nitrogen. This type of stainless steel has high strength, excellent corrosion resistance, and good welding properties, and is widely used in chemical, marine, shipbuilding, and other fields.
  • Cr22 Duplex Stainless Steel: Its chemical composition contains 22% chromium and about 6% to 8% nickel, as well as small amounts of molybdenum and nitrogen, and other elements. This type of stainless steel has higher strength and better corrosion resistance and is suitable for applications requiring higher strength and more severe corrosive environments, such as petroleum, chemical, marine, etc.
  • Cr25 Duplex Stainless Steel: It’s chemical composition contains 25% chromium and about 7% to 9% nickel, as well as small amounts of elements such as molybdenum and nitrogen. This type of stainless steel has higher strength and better corrosion resistance and is divided into two types: duplex and super duplex. Super duplex stainless steel has outstanding strength and corrosion resistance and is suitable for marine engineering, the chemical industry, shipbuilding, and other fields.
  • Cr23 Duplex Stainless Steel: This type of stainless steel does not contain molybdenum, but contains 23% chromium and 3% to 5% nickel, as well as a small amount of nitrogen and copper, and other elements. It has better corrosion resistance and higher strength and is suitable for use in acidic environments and some special working conditions.

Features of 2507 Stainless Steel Sheets and plates

Duplex stainless steel has the qualities of austenitic stainless steel and stainless steel since it has a ferritic structure, as well as they, are essentially exactly the same. The yield strength can attain 400Mpa 550MPa, which can be that of austenitic stainless steel. In comparison with ferritic stainless steel, duplex stainless steel has high toughness transition temperature and resistance to intergranular corrosion and reliability. At precisely the exact same time, it keeps some features of ferritic stainless steel, for example, 475 brittleness and warmth.
