Forta H-Series – Ultimate lightweight solutions with high strength austenitic materials

Abstract

Since 2012 Outokumpu developed a new lightweight steel group, called Forta Hseries, to its large industrial series readiness. The chromium-manganese alloyed material group (MnCr steels) is characterized by its full austenitic microstructure in combination with a special hardening effect which enables ultra-high strength properties and enormous energy absorption during crash. The Forta H-series is applicable over the complete automotive process chain because of its good similar and dissimilar weldability, a high formability for complex forming parts and a good paintability as well as a good corrosion protection system. The new austenitic material group makes a big contribution for higher passenger safety in future lightweight vehicles like passenger cars, commercial, agricultural or railway vehicles. Concurrently the material fulfills the social expectations in point of CO2 emission reduction and recyclability.
