PropertyValue / Reading
WeldabilityExcellent weldability using Nb-stabilized (ER347) or Ti-bearing filler metals; immune to intergranular corrosion in the 425 - 850 deg C sensitization range.
MachinabilityModerate; titanium carbonitrides increase tool wear slightly compared to SS304, requiring coated carbide tools.
Case HardeningHardenable only by cold working; stabilized for continuous service in elevated temperatures (425 - 900 deg C).
Corrosion ResistanceEquivalent general corrosion resistance to SS304 with superior resistance to intergranular attack in exhaust, aircraft, and refinery service.
