Compare all 7 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Soft Annealed | Delivery condition for machining/roughing of tool blanks before hardening. | 550 | 800 | 10 | 20 HRC | 2.9 % IACS |
Hardened & Tempered | Choose when chipping/cracking of slender punches or thick-plate blanking dominates over wear. | 1,750 | 1,900 | 1.5 | 58 HRC | 2.6 % IACS |
HT60Default Hardened & Tempered | Standard working hardness (≈1020–1050 °C austenitise, 3× temper 525–560 °C) — best wear/toughness balance. | 1,900 | 2,050 | 1 | 60 HRC | 2.7 % IACS |
Hardened & tempered 60 HRC + plasma nitrided | Diffusion case ~1100–1300 HV for extra surface wear resistance; case is brittle, avoid on sharp edges. | 1,900 | 2,050 | 0.8 | 60 HRC | 2.7 % IACS |
Hardened + deep cryogenic (−80/−196 °C) + tempered | Adds ~1 HRC and improves dimensional stability by removing retained austenite — for precision tools. | 1,950 | 2,100 | 1 | 61 HRC | 2.6 % IACS |
Hardened & Tempered | Higher austenitising/secondary-hardening temper for abrasive wear and high-strength-steel blanking. | 2,000 | 2,200 | 0.8 | 62 HRC | 2.6 % IACS |
Hardened & Tempered | Maximum hardness for pure abrasive wear / fine blanking of thin material; toughness margin is small. | 2,100 | 2,350 | 0.5 | 64 HRC | 2.5 % IACS |

What is Vanadis 4 Extra?
Vanadis 4 Extra is a SuperClean powder-metallurgy Cr-Mo-V cold-work tool steel from Uddeholm, supplied soft-annealed and heat treated to 58, 60, 62 or 64 HRC, with cryogenic, PVD-coated and nitrided variants on file. At 60 HRC it reaches about 2050 MPa tensile strength, and the balance of wear resistance and toughness suits blanking and cold-forming tooling that chips or cracks in conventional grades; usual forms are flat bar, plate and round bar. The steel is not stainless, is limited to roughly 450 °C service, and machinability of 18 plus PM pricing raise tooling cost, so D2 stays the cheaper option where chipping is not the failure mode. Vanadis 4 Extra has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 95% of steel grades. It melts at 1,290°C (2,354 °F). Vanadis 4 Extra has a yield strength of 1,900 MPa (276 ksi) and a tensile strength of 2,050 MPa (297 ksi) — stronger than 100% of steel grades. Elongation at break is 1% and the elastic modulus is 210 GPa (30.5 Msi).

Working with Vanadis 4 Extra
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 — frequently asked
What is Vanadis 4 Extra used for?
Vanadis 4 Extra 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?
Vanadis 4 Extra has a typical yield strength of 1,900 MPa (276 ksi) and a tensile strength of 2,050 MPa (297 ksi) — stronger than 100% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is Vanadis 4 Extra easy to machine?
Not especially — machinability is rated poor (18/100, worse than 97% 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 be welded?
Not readily — weldability is rated poor (18/100). 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 is the maximum service temperature of Vanadis 4 Extra?
Vanadis 4 Extra is rated for continuous use to about 450°C (842 °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.
