Working with Vanadis 4 Extra-HT62

Is Vanadis 4 Extra easy to machine?

Rough-machine in the soft-annealed state with sharp carbide/coated tooling and rigid setups; after hardening use grinding (SG/CBN wheels), hard turning with CBN, or wire/sinker EDM, and always stress-relieve after heavy EDM or rough cuts.

Can Vanadis 4 Extra be welded?

Only repair welding is recommended — preheat and hold at 200–250 °C, use matched or Cr-Mo-V tool-steel TIG filler, small stringer beads, slow cool and re-temper 20–30 °C below the original tempering temperature.

Can Vanadis 4 Extra be formed, bent or molded?

Not a formable grade; shape by machining and EDM in the annealed condition, then harden (1020–1080 °C, high-pressure gas quench) with 2–3 tempers of 2 h at 525–560 °C.

What surface finishes work on Vanadis 4 Extra?

Polishes cleanly thanks to the SuperClean PM microstructure; for anti-galling use PVD (TiCN, AlCrN) on a substrate tempered ≥ 525 °C, or plasma nitriding; store oiled or vapour-phase protected since the steel is not stainless.

Vanadis 4 Extra-HT62 — frequently asked

What is Vanadis 4 Extra-HT62 used for?

Vanadis 4 Extra-HT62 is typically used for cold forming dies, punches, knives and shear blades. In short: balanced PM cold-work steel; resists chipping better than D2; clean structure polishes well.

What is the yield strength of Vanadis 4 Extra-HT62?

Vanadis 4 Extra-HT62 has a typical yield strength of 2,000 MPa (290 ksi) and a tensile strength of 2,200 MPa (319 ksi) — stronger than 100% of steel grades. Strength varies by condition: see the 7 listed tempers.

Is Vanadis 4 Extra-HT62 easy to machine?

Not especially — machinability is rated not recommended (14/100, worse than 98% of steel grades). Rough-machine in the soft-annealed state with sharp carbide/coated tooling and rigid setups; after hardening use grinding (SG/CBN wheels), hard turning with CBN, or wire/sinker EDM, and always stress-relieve after heavy EDM or rough cuts.

Can Vanadis 4 Extra-HT62 be welded?

Not readily — weldability is rated poor (15/100). Only repair welding is recommended — preheat and hold at 200–250 °C, use matched or Cr-Mo-V tool-steel TIG filler, small stringer beads, slow cool and re-temper 20–30 °C below the original tempering temperature.

What surface finishes work on Vanadis 4 Extra-HT62?

Polishes cleanly thanks to the SuperClean PM microstructure; for anti-galling use PVD (TiCN, AlCrN) on a substrate tempered ≥ 525 °C, or plasma nitriding; store oiled or vapour-phase protected since the steel is not stainless.

Can Vanadis 4 Extra-HT62 be formed, bent or molded?

Not a formable grade; shape by machining and EDM in the annealed condition, then harden (1020–1080 °C, high-pressure gas quench) with 2–3 tempers of 2 h at 525–560 °C.

What is the maximum service temperature of Vanadis 4 Extra-HT62?

Vanadis 4 Extra-HT62 is rated for continuous use to about 480°C (896 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between Vanadis 4 Extra-HT60 and Vanadis 4 Extra-SA?

HT60 is the default condition — standard working hardness (≈1020–1050 °C austenitise, 3× temper 525–560 °C) — best wear/toughness balance. SA: delivery condition for machining/roughing of tool blanks before hardening. Yield strength is 1,900 MPa in HT60 versus 550 MPa in SA.
