Product Details:

MaterialDuplex 2205.2506.2507
Length10 - 500 mm
StandardDIN
SizeM6 -M64, 1/4"- 3"

duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

Features:
  • High resistance to chloride stress corrosion cracking
  • High Strength
  • Superior resistance to chloride pitting and crevice corrosion
  • Good general corrosion resistance
  • Suggested for applications up to 600° F
  • Low rate of thermal expansion
  • Combination of properties given by austenitic and ferritic structure

Mechanical properties:

  • The duplex micro structure and the alloying with nitrogen contribute to the high mechanical strength of the duplex grades. The high strength gives opportunities of weight saving and therefor cost savings in a number of applications, thinner gauges can be used with a duplex material compared to an austenitic material.

Physical properties:

  • The duplex grades have a lower coefficient of thermal expansion than the austenitic grades, close to that of carbon steel. Other physical properties are very similar to the properties of austenitic stainless steel.

Corrosion resistance:

  • The resistance to uniform and localized corrosion of the duplex grades increases with alloying content and the leaner grades like LDX 2101® and 2304 can be compared to the standard austenitic grades with and without molybdenum and the ferritic grade 4521 in chloride containing environments.
  • In the same way can the corrosion resistance of the super duplex grade 2507 be considered similar to the austenitic grade 254 SMO®. The duplex grades are superior to the standard austenitic grades when it comes to stress corrosion cracking, SCC, resistance. The duplex grades show good performance in a number of acidic and alkaline environments, a large number of tests has been carried out and the results are available in Corrosion Handbook.

Fabrication:

  • Duplex stainless steel is suitable for all forming processes available for stainless steel. The high proof strength compared to austenitic and ferritic stainless steel can impose some differences in forming behaviour depending on chosen forming technique, such as an increased tendency to spring back. This point is particularly relevant to forming of any high strength steel.
  • Duplex steels generally have good weldability and can be welded with most of the welding methods used for austenitic stainless steel, but parameters like heat input and speed needs to be modified when changing from austenitics to duplex.
