What Is Dillimax 690T Plate & Why Do Structural Engineers Prefer It?

Dillimax 690T is a quenched and tempered structural steel manufactured by Dillinger Hütte (Germany). It offers a minimum yield strength of 690 MPa, combining excellent toughness, fatigue strength, and weldability. Engineers and designers choose this grade for:

  • Weight reduction without compromising safety
  • High performance under dynamic loads
  • Low-temperature toughness (charpy impact at -40°C)

It is a go-to choice for applications where structural integrity, light weight, and high stress resistance are critical.

Industrial Applications of Dillimax 690T Plates

Dillimax 690T plates are widely used in:

  • Telescopic cranes & mobile cranes
  • Hydraulic boom arms & lifting jibs
  • Heavy trailers and equipment chassis
  • Shipbuilding & offshore platform components
  • Bridge structures, gantries & high-load frames
  • Mining equipment & bulk material handling systems

Its low carbon equivalent and micro-alloyed composition enable both strength and weldability.

Mechanical Properties of Dillimax 690T Steel

Property Typical Value
Yield Strength (min) 690 MPa
Tensile Strength 770 – 940 MPa
Elongation 14 – 17%
Impact Toughness ≥ 40J at -40°C
Heat Treatment Quenched & Tempered
Thickness Availability 6 mm to 150 mm

Plates are supplied with EN 10204 3.1 or 3.2 certification, tested as per EN 10025-6 standards.

Technical Standards & Global Equivalents of Dillimax 690T

Dillimax 690T is produced according to EN 10025-6 standards under proprietary Dillinger norms. Its common equivalents include:

  • S690QL (EN 10025-6)
  • ALFORM 700 M
  • Weldox 700 / Strenx 700
  • JFE Hiten 780 LE
  • ASTM A514 Grade Q (approximate)

However, Dillimax 690T remains preferred due to its ultra-clean steelmaking process, tight tolerances, and consistent low-temperature impact strength – all certified by Dillinger.

Available Thickness, Width & Length Range

We supply cut-to-size Dillimax 690T plates as per project drawings with mill test certificates.

  1. Thickness: 6 mm to 150 mm
  2. Width: Up to 3000 mm
  3. Length: Up to 12000 mm (or custom cut)
  4. Tolerances: EN ISO 18286 Class A/B (optional)

Custom rolling options are available for large quantity orders.

Quenching, Tempering & Low-Temp Toughness

Dillimax 690T undergoes precision quenching and tempering treatment at Dillinger’s high-tech facilities. The result:

  • Superior microstructure (ferrite-bainite)
  • Guaranteed toughness at -40°C
  • Uniform hardness across plate thickness

This heat treatment allows safe fabrication and ensures resistance to brittle fracture, ideal for offshore and crane boom components.

Fabrication, Cutting & Welding Guidelines

Despite its high strength, Dillimax 690T is easy to work with due to its:

  • Low carbon equivalent (~0.4 CE)
  • Excellent weldability using MAG, SAW, or TIG
  • Cold forming capacity (with preheat over 30 mm)
  • Good machinability for drilling, tapping, and counterboring

Note: Use matching filler wire (EN ISO 16834-A) for structural integrity in welds.
