DILLIMAX

The steel for lightweight designs: DILLIMAX

DILLIMAX is one of the most versatile Dillinger Hütte GTS branded grades - a very special structural steel. It can be used, for example, where the scale of the design means that every kilogram saved is a vital benefit - as in the case, for example, of large crane jibs and booms, heavy-duty travel gear, offshore structures, and bridges. DILLIMAX is also the rational choice for achievement of support structures with striking aesthetics, as are so frequently encountered in contemporary architecture. DILLIMAX not only facilitates such designs, it actually makes them safer - this steel combines maximum mechanical strength with outstanding toughness and unusually good workability.

It also has extremely good suitability for cold-working and machining. Above all, however, it possesses amazingly good weldability - so good, in fact, that stress-relieving annealing after component completion is usually not necessary. With this combination of properties, DILLIMAX goes well beyond the standardized requirements contained, for example, in EN 10025. Water-quenching and tempering imparts these special properties to DILLIMAX. This steel is available at a number of strength levels, which are identified by its minimum yield strength: DILLIMAX 460, DILLIMAX 500, DILLIMAX 550, DILLIMAX 890, DILLIMAX 965 and DILLIMAX 1100.

Special DILLIMAX qualities

The following special qualities have been developed for particular applications:

DILLIMAX 500 ML: High strength at low temperatures

DILLIMAX 500 ML is a steel distinguished by its exceptionally good low-temperature toughness. It is the only steel of the DILLIMAX series which is not water-quenched and tempered, instead being produced via the thermomechanical rolling route. DILLIMAX 500 ML is supplied in plate thicknesses of between 10 and 80 millimeters and with an impact energy verified down to -50° C.

DILLIMAX 690 PE: Utilisation for the construction of pressure equipment

DILLIMAX 690 PE is a variant of DILLIMAX 690 and has been developed specially for use in pressure-vessel engineering; its mechanical properties and chemical composition conform to the specifications of Grade P690Q (1.8879) as standardized in EN 10028, Part 6: 2003.

DILLIMAX TL is generally used for the fabrication of telescopic booms of earth moving and structural machinery

DILLIMAX TL plates are plates with higher requirements for both dimensions and flatness tolerances.
