Steel Strength, the Backbone of the Automotive Industry

Описание: For decades, the steel industry has pioneered a whole new class of materials that are 50% stronger than their predecessors. At the core of this innovation lies the ever-growing Advanced High-Strength Steel (AHSS) family. No other automotive material compares to the variety of steel strength levels today.

This means that the steel can be made thinner, yet retain its strength for vehicle structure performance and safety. Thinner material means less material is used, and therefore components are lighter, contributing to vehicle weight reduction and reduced environmental emissions. Because primary manufacture of steel produces fewer emissions than any other automotive material, it's a win-win, both in terms of reduced steel manufacturing and vehicle emissions.

These AHSS capabilities result from their unique combination of strength and ductility. AHSS are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes. Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties.
