German producer of high end plates Dillinger announced that it has further developed DILLINAL as a special solution for transportable tanks. Using this weld able, fine-grained structural steel, notable for an even more remarkable combination of mechanical strength and toughness, Dillinger exhaustively exploit all potentials for minimizing the tare, boosting transportation payloads and thus improves the CO2 balance for the product transported. In addition, Dillinger significantly improves the welding processing for the fabrication shop. To achieve the normalized 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 normalized 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. 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 fulfills the standard's requirement for HP factor and actually has the potential to achieve slightly higher HP values.
