In comparison to grades 904L or 6% moly, the content of nickel in stainless steel grade 2507 is significantly lower. Both the former alloys contain nickel content ranging between 24% to 28%, as opposed to 2507 Super duplex fasteners, which makes use of only 7% nickel. Nickel is a costly metal, and using it at a higher level brings up the cost of the alloy. But since the Super Duplex Fasteners Manufacturer would use only 7% nickel of the total weight of the alloy, this particular metal has proven itself to be a cost effective solution amongst other alloys.

Belonging to the duplex category of stainless steels, the Super Duplex Nuts And Bolts are a superior grade in comparison to grade 2205. The corrosion resistance properties, as well as the tensile properties of Super Duplex Stainless Steel Bolt, are far better in comparison to grade 2205, making them a super duplex alloy. Another important property of the Super Duplex 2507 Fasteners is that they demonstrate outstanding levels of resistance to chloride induced SCC or stress corrosion cracking.

Steels that are highly ductile are prone to failure by SCC. the dual microstructure that includes ferrite in combination with its high chromium chemistry makes the Super Duplex Bolts And Nuts resilient to failure from SCC. Speaking of corrosion, the alloy has great resistance to intergranular corrosion. High chromium steels that have a significant content of carbon tend to undergo intergranular corrosion. The low content of carbon in Super Duplex Stud Bolts prevents the formation of carbide precipitates reducing its vulnerability to intergranular corrosion.

Weldability of Super Duplex 2507 Fasteners
  • Preheating is not necessary, except to prevent condensation on cold metal.
  • Surfaces must be clean before welding.
  • The interpass temperature should not exceed 150 deg C.
  • It possesses good weldability and can be welded to itself and other materials by Shielded Metal Arc Welding (SMAW), GasTungsten Arc Welding (GTAW), Plasma Arc Welding (PAW) or Submerged Arc Welding (SAW).
  • The root should be shielded with commercial Ar or 90%N2 / 10%H2 purging gas for maximum corrosion resistance
  • The recommended heat input should be nearly about 0.3-1.5K1/mm
