Nickel Alloy Socket Weld Fittings


These nickel alloy Socket Weld Fittings are used extensively in applications where heat resistance and/or corrosion resistance is required. Nickel Alloy Socket Weld Fittings in this class are designed to resist failure from both of these mechanisms. Nickel alloy Socket Weld Fittings are not suitable for high temperature sulphur rich environments.This nickel alloy Socket Weld Fittings are frequently sold under trade name specifications but most are listed in the Unified Numbering System. Common trade names are HASTELLOY, INCOLOY, INCONEL, NICROFER, NICROM and NIMONIC.
Nickel alloys Socket Weld Fittings have higher strength and longer life at elevated temperature than most alloys. The designer however, must determine the expected life of each component and use the appropriate creep and rupture strength in the design before selecting Socket Weld Fittings.

    Iron-Nickel-Chromium Alloys Socket Weld Fittings. This series of alloy Socket Weld Fittings has also found extensive use in the high-temperature petrochemical environments, where sulfur-containing feedstocks (naphtha and heavy oils) are cracked into component distillate parts. Not only were these Socket Weld Fittings resistant to chloride-ion stress-corrosion cracking, but they also offered resistance to polythionic acid cracking. Some alloys of commercial importance include:
  • Nickel Alloy 800 (Fe-32Ni-21Cr) Socket Weld Fittings -The basic alloy in the Fe-Ni-Cr system; resistant to oxidation and carburization at elevated temperatures.
  • Nickel Alloy 800HT Socket Weld Fittings -Similar to 800H with further modification to combined titanium and aluminum levels (0.85 to 1.2%) to ensure optimum high-temperature properties.
  • Nickel Alloy 801 Socket Weld Fittings -Increased titanium content (0.75 to 1.5%); exceptional resistance to polythionic acid cracking.
  • Nickel Alloy 802 Socket Weld Fittings -High-carbon version (0.2 to 0.5%) for improved strength at high temperatures.
  • Nickel Alloy 825 (Fe-42Ni-21.5Cr-2Cu) Socket Weld Fittings -Stabilized with titanium addition (0.6 to 1.2%). Also contains molybdenum (3%) for pitting resistance in aqueous corrosion applications. Copper content bestows resistance to sulfuric acid.
  • Nickel Alloy 925 Socket Weld Fittings -Addition of titanium and aluminum to 825 composition for strengthening through age hardening.
