The automotive industry is witnessing a demand in higher standards for passenger safety, vehicle performance and fuel economy. The problem: Advanced high-strength (AHS) steels, commonly used in car body structures to absorb impacts, become brittle and sometimes break due to welding and hot stamping processes.
However, a solution is in sight an…
