Duplex 2507 Overview
Duplex 2507 is a super 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.
Usage of Duplex 2507 should be limited to applications below 600° F
(316° C). Extended elevated temperature exposure can reduce both
the toughness and corrosion resistance of alloy 2507.
Duplex 2507 possesses excellent mechanical properties. Often a
light gauge of 2507 material can be used to achieve the same design
strength of a thicker nickel alloy. The resulting savings in weight
can dramatically reduce the overall cost of fabrication.
Corrosion Resistance
2507 Duplex is highly resistant to uniform corrosion by organic
acids such as formic and acetic acid. It is alsohighly resistant to
inorganic acids, especially if they contain chlorides. Alloy 2507
is highly resistant to carbide-related intergranular corrosion. Due
to the ferritic portion of the duplex structure of the alloy it is
very resistant to stress corrosion cracking in warm chloride
containing environments. Through additions of chromium, molybdenum
and nitrogen localized corrosion such as pitting and crevice attack
are improved. Alloy 2507 has excellent localized pitting
resistance.
What are the characteristics of Duplex 2507?
• 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
• Low rate of thermal expansion
• Combination of properties given by austenitic and ferritic
structure
• Good weldability and workability
