Super Duplex 2507

At Atlanta Rod and Manufacturing Co., Inc. we strive to provide our customer with the most innovative and quality materials and products in the industry.  It is for that reason that Atlanta Rod manufactures Super Duplex 2507 hex bolts, nuts, and screws to your custom specifications, and we guarantee to meet your delivery schedule.

Super Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Super Duplex 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 Super Duplex 2507 with exceptional resistance to chloride stress corrosion cracking.

Usage of Super 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.

Super Duplex 2507 possess excellent mechanical properties. Often a light gauge of Super Duplex 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.

Some of the benefits  of Super Duplex 2507 include: good weldability and workability, a high level of thermal conductivity and low coefficient of thermal expansion, high resistance to corrosion, fatigue, high resistance to pitting and crevice corrosion, high resistance to stress corrosion cracking (especially chloride stress corrosion cracking), high energy absorption, high strength, and erosion. Essentially, the Duplex alloys are a compromise; possessing some of the ferritic stress corrosion cracking resistance and much of the superior formability of the common austenitic stainless alloys, more cost effectively than the high nickel alloys.
