PropertyValue / Reading
WeldabilityGood by TIG and MIG with low heat input and interpass temperature below 100 deg C using matching 904L or Ni-Cr-Mo filler.
MachinabilityChallenging due to high nickel content and rapid work-hardening; requires low cutting speeds, rigid setup, and sharp PVD-coated carbide tools.
Case HardeningFully austenitic, non-magnetic structure; cannot be hardened by thermal treatment.
Corrosion ResistanceExceptional resistance to sulfuric, phosphoric, and acetic acids (aided by 1.5% Cu), chloride stress-corrosion cracking, and warm seawater.
