High-Strength Steels MAXIL®
With our MAXIL® steel grade, we meet the highest production requirements of a wide range of consumers. The high-strength, weldable fine-grained structural steel MAXIL® achieves its characteristic combination of high strength values and excellent toughness properties thanks to its finely dispersed quenched and tempered structure. Compared with conventional structural steels, MAXIL® is therefore characterized by its lower dead weight combined with higher load-bearing capacity and reduced welding costs. For the consumer, this means higher added value and expanded construction possibilities.
ILG has been successfully producing the high-strength steels of the MAXIL® range for over 25 years. The experience gained has been taken into account and implemented in the design of our new heat treatment line. After successful testing, we now offer a product with improved processing properties up to a guaranteed yield strength of up to 1300 MPa. Flatness and surface quality have been significantly improved.
These improvements are made possible by a modified process technology. First, the sheets are pre-blasted to produce a clean, scale-free surface. Heating then takes place in a highly energy-efficient furnace. Since the entire furnace chamber is filled with nitrogen, renewed scaling is prevented. Damage to the sheet surface, e.g. due to an accumulation of scale residues and resulting indentations in the hot sheet surface, is ruled out here. A further decisive advantage is also the direct cooling of the steel surface in the quette. Uneven or delayed cooling by the scale is ruled out.
The heart of the new heat treatment line is the multifunctional quench. Water distribution is specifically matched to the respective plates, enabling the production of consistently high quality.
The design of the chemical composition used in MAXIL® steels, is aimed at very good processing properties, without compromising the properties to be guaranteed. Lowering of preheating temperatures during further processing, improved formability and high toughness level characterize our steel. This is achieved by reducing alloying elements. For example, in the case of plates up to medium plate thicknesses, while maintaining the same mechanical / technological properties, the proportion of carbon has been reduced by 25%.
