Nickel content in stainless steel grade 2507 is considerably lower than that of grades 904L or 6 percent moly. Compared to 2507 Super duplex fasteners, which use only 7% nickel, each of the former alloys have nickel content ranging from 24 to 28 percent. Because nickel is an expensive metal, adding more of it to an alloy raises its price. However, compared to other alloys, this specific metal has shown itself to be a cost-effective alternative because the manufacturer of super duplex fasteners would only need 7% nickel of the entire weight of the alloy.

The Super Duplex Nuts and Bolts are a better grade than grade 2205 in the duplex category of stainless steels. Super Duplex Stainless Steel Bolts are a super duplex alloy because they have significantly greater corrosion resistance and tensile qualities than grade 2205. The Super Duplex 2507 Fasteners also exhibit exceptional levels of resistance to chloride-induced SCC, also known as stress corrosion cracking.

Highly ductile steels are vulnerable to SCC failure. The Super Duplex Bolts And Nuts are resistant to failure from SCC due to its high chromium chemistry and dual microstructure that contains ferrite. The alloy has excellent resistance to intergranular corrosion, speaking of which. When high chromium steels include a lot of carbon, intergranular corrosion frequently occurs. Super Duplex Stud Bolts' low carbon content prevents carbide precipitates from forming, lowering their susceptibility to intergranular corrosion.

Weldability of Super Duplex 2507 Fasteners
  • The interpass temperature should not exceed 150 deg C.
  • The root should be shielded with commercial Ar or 90%N2 / 10%H2 purging gas for maximum corrosion resistance
  • 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).
  • Preheating is not necessary, except to prevent condensation on cold metal.
  • The recommended heat input should be nearly about 0.3-1.5K1/mm
  • Surfaces must be clean before welding.
