Theoretical Foundations of the Hot Stamping of Ultra-High-Strength Boron Steel: The Case of B1500HS with 22MnB5 and BR1500HS as Benchmark Grades
The hot stamping of boron-alloyed steel integrates forming with in-die quenching and is a core route to 1500 MPa class automotive safety components, yet its parameter design still lacks a unified theoretical basis. This article critically reviews the theoretical foundations of the process and establishes a framework co...
