Looking for a reliable supplier of NAXTRA 70 quenched and tempered steel plates in India? Hindustan Steel Corporation delivers precision-engineered plates for structural, automotive, and heavy-duty engineering projects — ready in cut-to-size form with mill test reports and rapid export support.
Designed for superior tensile performance and weldability, NAXTRA 70 plates are widely used in crane manufacturing, load-bearing frames, and yellow goods — where strength, weight reduction, and fatigue resistance are critical.
Available in widths up to 3000mm and thickness from 6mm to 150mm
EN 10025-6 compliant – German-make & equivalent grades in stock
High notch toughness, bendability & excellent weld performance
NAXTRA 70 is a high-strength low-alloy (HSLA) steel that undergoes quenching and tempering (Q&T) to achieve its mechanical properties. Produced by Dillinger Hütte or equivalent European mills, this grade delivers a minimum yield strength of 690 MPa and combines:
These features make NAXTRA 70 ideal for construction equipment, lifting beams, truck chassis, and crane booms.
Due to its consistent yield-to-tensile ratio, excellent elongation percentage, and tight thickness tolerances, NAXTRA 70 is commonly used in:
| Property | Typical Value |
|---|---|
| Yield Strength (Min) | 690 MPa |
| Tensile Strength | 770–940 MPa |
| Elongation (L0 = 5.65√S0) | ≥ 14% |
| Impact Test (Charpy V) | ≥ 40J at -40°C (for thickness <50mm) |
| Brinell Hardness (HB) | 250–290 HBW (typical) |
NAXTRA 70 is typically produced in accordance with EN 10025-6 standards and matches several international equivalents. The plates adhere to tight mechanical tolerances and undergo stringent mill testing.
Common equivalents include:
| Standard | Equivalent Grade |
|---|---|
| EN 10025-6 | S690QL |
| DIN | NAXTRA 70 (original mill) |
| AFNOR | E690T |
| ASTM | A514 Grade Q (approx.) |
Mill supplies available with EN 10204 3.1 / 3.2, CE marking, and ultrasonic tested options (UT EN 10160).
At Hindustan Steel Corporation, we stock cut-to-size NAXTRA 70 steel plates with the following dimensional capabilities:
Large-width plates are ideal for beams, long weldments, and chassis frames where deflection resistance is key.
NAXTRA 70 plates are manufactured via a two-stage heat treatment process:
The result? A balanced microstructure that delivers high strength without sacrificing formability or toughness.
This treatment enables use in dynamic loading conditions, offshore structures, and heavy wear applications.
Despite its high tensile nature, NAXTRA 70 is fabrication-friendly, provided basic precautions are followed:

Here’s how buyers can ensure the correct NAXTRA grade is selected for their needs:
| Requirement | NAXTRA Plate Choice |
|---|---|
| High weldability + toughness | NAXTRA 70 (standard) |
| Better elongation + forming | NAXTRA 700 (low temp use) |
| Weight reduction, high payload | Combine NAXTRA 70 with 550 or 650 variants |
| German-origin quality preference | Dillimax 690T or NAXTRA Xabo |
Tip: Always check impact testing requirements (CVN @ -20°C / -40°C) for offshore and mobile equipment projects.
