The microstructure of AFP steel usually consists of a mixture of ferrite and pearlite, similar to conventional ferritic-pearlitic steels. However, AFP steels are produced using advanced processing techniques such as controlled rolling and accelerated cooling, which help to refine the microstructure and improve the mechanical properties.
High-strength reinforcing steel for slender structures and cost-effective construction
The high-strength micro-alloyed reinforcing steel enables greater flexibility and stability for the most demanding requirements, developed by Steeltec in Switzerland.
With a yield strength of more than >700 N/mm2, the special steel Top700 is ideally suited for
Increasing strength and reducing steel quantities
Top700 solves several challenges that other reinforcing steels cannot. Thanks to its higher yield strength of >700N/mm2, Top700 overcomes technical constraints, such as space problems with the reinforcement or aesthetic challenges, such as reducing the concrete cross-section. And it also offers economic advantages, as up to 40% less steel is required due to the higher strength, which leads to cost savings in several areas: lower quantity, less processing effort, less transportation. The latter is also a welcome factor from an environmental point of view.
High-strength Top700 means less reinforcement
This opens up new possibilities for architectural design: slimmer construction with better use of space and less weight. The amount of work in prefabrication and on the construction site is reduced as less steel is required. The standard values for the maximum reinforcement ratio in highly reinforced components are easier to comply with. Reinforced concrete construction with Top700 does not require any special properties from the concrete.
