DILLINAL was further developed as a special solution for transportable tanks. Using this weldable, fine-grained structural steel, notable for an even more remarkable combination of mechanical strength and toughness, we exhaustively exploit all potentials for minimising the tare, boosting transportation payloads and thus improves the CO2 balance for the product transported. In addition, we significantly improve the welding processing for the fabrication shop.
Minimising tare and thus boosting transportation payloads, together with operational safety, is the most important goal of the designers of transportable pressure equipment. This is precisely where Dillinger's research and development has come in to exploit the possibilities of normalised steels within the framework of the applicable regulations.
To achieve the normalised fine-grained DILLINAL structural steel, the conventional P460NH described in EN 10028, Part 3, was further developed and improved. DILLINAL obtains its typical properties thanks to an extremely tightly defined composition window and exact temperature control during rolling and heat treatment. The result is a high-strength normalised fine-grained structural steel with an excellent combination of mechanical strength and toughness. In both its chemical composition, mechanical characteristics and welding requirements, DILLINAL in all cases conforms to the EN 10028, Part 3 standard and thus already meets the expanded requirements stated in Option 5 (Paragraph 7.2. of EN 10028, Part 3).
The excellent properties of DILLINAL are self-evident, but not enough for our requirements. In addition to this steel's already excellent properties, we have also incorporated improved weldability. This enables the steel user to work with higher specific heat inputs and to fulfil the required toughness level in the weld with certainty.
The predicted and observed tensile and yield strength data are in all cases above the minimum levels required in EN 10028, Part 3, even at elevated temperatures.
DILLINAL exhibits virtually no loss in tensile and yield strength data in the significant material reaction to stress-relieving heat treatment. DILLINAL also excellently fulfils the standard's requirement for HP factor and actually has the potential to achieve slightly higher HP values.
