PropertyValue / Reading
WeldabilityModerate; requires preheating to 250 - 350 deg C and immediate post-weld stress relief.
MachinabilityGood in annealed state (approx. 75% of 1% carbon tool steel).
Case HardeningOil-hardening shock-resisting steel; can also be carburized at 900 - 920 deg C to combine a wear-resistant case (60 HRC) with a tough core.
Corrosion ResistanceLow natural resistance; requires oiling or protective coatings against rust.
