Sheetmetal for hot stamping is obtained from HSS (High Strength Steel) or UHSS (Ultra High Strength Steel) and as they were put to the market, the realization of automotive components has changed a great deal.
High strength steels feature a low carbon and microalloyed elements content.
These products are extremely ductile, furthermore their yield strength is high just like their mechanical resistance, thanks to their chemical purity ant to their very thin microstructure.
The consistency and the uniformity of their features make them suitable for the various processing modes, even though the stampability degree is inversely proportional to the mechanical resistance. They normally are quite resistant to stress and impact.
