PropertyValue / Reading
WeldabilityPoor; welding is recommended only for tool repair with preheating (350 - 450 deg C) and matching D2 filler.
MachinabilityRated at approx. 40 - 45% of W1 water-hardening tool steel; high vanadium carbide content requires rigid tooling.
Case HardeningDeep air-hardening steel with minimal distortion; secondary hardening response permits surface nitriding or PVD coating.
Corrosion ResistanceGood resistance to mild organic acids and humidity when hardened and mirror-polished.
