NLMK Verona Tool Steel DB6 (DIN 1.2714): Properties, Applications & Supply in India
If you own a forging shop, die-making unit or heavy tooling operation, you know that the difference between a die that lasts one production run and one that lasts hundreds comes down to the steel underneath it. NLMK Verona Tool Steel DB6 is one of the European grades that is increasingly being specified by Indian manufacturers for close die forging, hammer dies and heavy-impact tooling – and with good reason.
This guide will explain what NLMK Verona DB6 really is, its real composition and mechanical properties, how it machines and heat-treats, where it is used and how to decide if it is the right grade for your application – all from verified technical data.
What Is NLMK Verona Tool Steel DB6?
NLMK Verona Tool Steel DB6 is a specialty tool steel plant of the NLMK Group, located in the north of Italy, close to Verona. The plant produces forged blocks, plates, and ingots for tool and die applications, and currently supplies its hot-work die steel to the Indian market under the DB6 designation — the specific grade Virat Steels stocks and distributes from this mill.
DB6 is not a proprietary or obscure code. It corresponds to well-established international standards:
| Designation | Standard |
| DB6 | Commercial/trade name |
| DIN 1.2714 | German (Werkstoff) standard |
| AISI L6 | American standard |
| AFNOR 55NCDVV7 | French standard |
| Standard family | 55NiCrMoV (Cr-Ni-Mo-V alloyed hot-work steel) |
To summarize, a buyer searching for “NLMK Verona DB6”, “db6 nmlk verona” or “nmlk verona die steel” is looking for this specific chromium-nickel-molybdenum-vanadium alloyed hot-work die steel, a popular grade in the European and Indian tooling supply chains, now available from NLMK Verona’s Italian production.
Chemical Composition of NLMK Verona Tool Steel DB6 / DIN 1.2714
DB6 is a Cr-Ni-Mo-V alloy system which provides a balance of toughness and hardness:
| Element | C | Si | Mn | P | S | Cr | Ni | Mo | V |
| % Range | 0.50–0.60 | 0.10–0.40 | 0.65–0.95 | ≤0.03 | ≤0.03 | 1.00–1.20 | 1.50–1.80 | 0.45–0.55 | 0.07–0.12 |
DB6 has high toughness and impact resistance (compared to more common hot-work grades such as H13) and high nickel content (compared to more common hot-work grades such as H13) for exceptional toughness and impact resistance rather than pure high-temperature hardness retention.
Mechanical Properties
| Property | Value |
| Tensile Strength | 1000–1400 MPa |
| Yield Strength | 1045 MPa |
| Elongation | 15%–20% |
| Impact Toughness | 20–25 J/cm² |
| Hardness (working) | 50–55 HRC |
| Compressive Strength | 2500 MPa |
| Modulus of Elasticity | 205 GPa |
Typical supply hardness ranges (depending on treatment condition):
- Annealed condition: 255 BHN max
- Hardened & tempered: 38–42 HRC (die-ready condition), with tools further hardened up to 50–55 HRC for service
- Hardness variation, surface to core: 20–25 BHN
Physical Properties
| Coefficient of Thermal Expansion (10⁻⁶ m/m·K) | 20–100°C | 20–200°C | 20–300°C | 20–400°C | 20–500°C | 20–600°C |
| Value | 12.1 | 13.1 | 13.2 | 13.5 | 14.1 | 14.3 |
| Thermal Conductivity (W/m·K) | 20°C | 350°C | 700°C |
| Value | 35.0 | 39.0 | 36.0 |
Note: Exact physical values can vary slightly with heat treatment and section size — always cross-check against the mill test certificate for critical applications.
Machinability of NLMK Verona DB6
DB6 is easy to work and the machinability can be rated at about 90 % relative to W-group water-hardening low-alloy steels taken as the 100 % reference. This makes it much easier to machine than many high-alloy cold-work or high-speed steel grades, and still retains the toughness needed for heavy forging dies.
Practical machining notes:
- Best machined in the annealed condition (≤255 BHN) before final hardening
- Finish machining should ideally be completed before final hardening and tempering, with only grinding/polishing done after
- Stress-relief before hardening reduces distortion risk in large die blocks
Heat Treatment Guide
| Process | Parameters |
| Annealing | Soak at 740–760°C, furnace-cool at max 10°C/hr down to 600°C, then air cool |
| Hardening | Preheat to 650°C, raise quickly to 900–950°C, quench in oil |
| Hardening (mill data) | 840–880°C oil quench → 57 HRC; 860–900°C air quench → 55 HRC |
| Tempering | Multiple tempers; hardness drops from ~56 HRC (100°C temper) to ~34 HRC (650°C temper) |
| Stress Relieving | Heat to 600–650°C, soak 2 hrs per 25mm section, slow cool |
| Forging | Warm to 700°C, raise to 1050°C, keep forging above 800°C, cool slowly in furnace/vermiculite |
| Nitriding | Possible after hardening + tempering; done ~50°C above nitriding temperature |
| Normalizing | Not recommended — DB6 is air-hardening |

How to Choose Between NLMK Verona Tool Steel DB6 (and Other Grades)?
- Is your tooling exposed to repeated impact/shock loading? DB6 is specifically strong here — hammer forging and heavy press dies benefit most from its toughness.
- Is your process purely high-temperature (die casting, hot extrusion) with less shock? H13 (DIN 1.2344) may be a better fit than DB6 due to superior thermal fatigue resistance.
- What supply condition do you need? DB6 is available annealed or hardened & tempered — confirm this at order stage based on your in-house heat treatment capability.
- What section size does your die need? Large forged blocks require good through-thickness hardenability — DB6’s alloy design supports this.
- Do you need surface hardening? DB6 can be nitrided after hardening/tempering for improved wear resistance while keeping core toughness.
- Do you need ultrasonic-tested quality die blocks? Ask specifically for extra forging reduction and double-tempered blocks — Virat Steels supplies DB6 this way for critical forging applications.

Same Chemistry on Paper, a Different Story on the Ground
On a certificate, Lucchini DB6 Tool steel and local DB6 tool steels can look almost identical — both fall within the same DIN 1.2714 tool steels chemical window. The real difference shows up upstream of the numbers, in how tightly that chemistry is held, batch after batch, and how clean the steel is once it’s melted and forged.
| Element | Lucchini DB6 / 1.2714 (%) DOCX | Standard Local 1.2714 (%) DOCX | Metallurgical Function DOCX |
| Carbon (C) | 0.50 – 0.60 | 0.50 – 0.60 | Controls baseline hardness and yield strength. |
| Silicon (Si) | 0.10 – 0.40 | 0.10 – 0.40 | Increases oxidation resistance and strength. |
| Manganese (Mn) | 0.60 – 0.95 | 0.60 – 0.95 | Enhances deep hardenability. |
| Chromium (Cr) | 0.80 – 1.20 | 0.80 – 1.20 | Enhances wear resistance and hardenability. |
| Molybdenum (Mo) | 0.35 – 0.55 | 0.35 – 0.55 | Retains high-temperature yield strength. |
| Nickel (Ni) | 1.50 – 1.80 | 1.50 – 1.80 | Primary driver for extreme impact toughness. |
| Vanadium (V) | 0.07 – 0.15 | 0.05 – 0.15 | Refines grain structure and carbide formation. |
| Phosphorus (P) | max 0.015 | max 0.030 | Kept low to prevent cold shortness/brittleness. |
| Sulfur (S) | max 0.010 | max 0.030 | Kept low to preserve steel cleanliness and fatigue life. |
Key takeaway: nominal composition alone doesn’t separate premium DB6 from ordinary DB6 tool steels. What matters far more is the consistency of chemistry control, steel cleanliness, and manufacturing discipline behind that certificate — and that is precisely where an established European mill like Lucchini has a structural advantage over less consistent local supply.

Why Manufacturers Choose Lucchini Tool Steel
Greater Resistance to Wear
Designed for hard working conditions and repeated production cycles, Lucchini grades minimise edge wear and reduce the frequency of maintenance shutdowns — keeping production lines running longer.
High Toughness
Good for tooling subjected to shock, impact and heavy mechanical loads where brittle fracture is costly. Lucchini’s controlled microstructure delivers consistent toughness that standard grades cannot match.
Thermal Fatigue Strength
Critical for die casting, forging, and extrusion where tools are repeatedly heated and cooled. Lucchini hot work grades resist thermal cracking even in high-cycle aluminium die casting operations.
Dimensional Stability
Maintains tolerances after heat treatment and in production — essential for precision tooling where dimensional drift causes part rejection.
Steady Production Performance
Cleaner steel and uniform properties allow for repeatable machining, heat treatment, and shop floor results batch to batch — reducing uncertainty in your toolroom.
