The specific addition of nitrogen in ASME SB 423 Nickel-Iron-Chromium-Molybdenum-Copper Seamless Tubes promotes structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. The two phase microstructure of ASTM B423 Nickel-Iron-Chromium-Molybdenum-Copper Alloy Pipes guarantees higher resistance to pitting, stress corrosion cracking, corrosion fatigue, crevice corrosion and strong weldability in comparison with conventional stainless steels.

ASME SB 423 Nickel-Iron-Chromium-Molybdenum-Copper Alloy Tubes is similar to Grade 321 with respect to inter – granular corrosion which is achieved through the use of columbium as a stabilizing element to maximize this feature. The nickel content of ASTM B423 Nickel-Iron-Chromium-Molybdenum-Copper Alloy Seamless Pipes aids in its chloride ion stress and corrosion resistance. ASME SB 423 Nickel-Iron-Chromium-Molybdenum-Copper Alloy Seamless Tubes combines outstanding resistance to oxidizing media with superior resistance to non – oxidizing environments and represents a true performance breakthrough for chemical process equipment applications.
