A case study for a worn tool steel in the hot stamping process

A good understanding of failure mechanisms can help us improve the lifetime of the dies. This paper presents a case study investigating the wear behaviour of a QRO90 die insert utilized for stamping uncoated boron-alloyed high-strength steel sheets. Topography and microstructure were characterized b...
