Development of low-temperature hot stamping technology for medium-mn steel
Hot stamping is an advanced technology for forming ultra-high-strength steels (UHSS), giving good formability and negligible springback. Medium-Mn (MMn) steels are one of the classes of third-generation advanced high-strength steels that have attracted ...

MBW 1200 – Hot Stamping Steel with Increased Ductility
Abstract Hot stamping steels are trending towards increased ductility without sacrificing too much stiffness. Thus a new aluminum silicon coated grade, MBW 1200 + AS has been developed, with typical yield strength after hot stamping and paint baking of YS ≈ 1000 MPa, tensile strength TS ≈ 1200 MPa and A80 > 5.0 ...

A novel method for the spring-back analysis of a hot stamping steel
Spring-back of sheet metal affects the dimensional accuracy of the components after stamping and has to be eliminated or corrected. Advanced high strength steels (AHSS) are prone to spring-back while forming at ambient temperatures.

Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts
Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to hardening by means of the ...

Effect of Microstructures on Yield Strength in Hot-Stamped Steel Sheet
For automotive structural parts, hot stamping is being increasingly used because of the need for both higher fuel efficiency and crashworthiness. The yield strength of hot-stamped steel sheet is lower than that of water-quenched steel sheet.

Effect of quenching rate on hardness and microstructure of hot-stamped steel
The effect of cooling rate on hardness and microstructure of the hot-stamped boron steel with 0.2 mass% carbon was investigated. After sheet specimen with a thickness of 1.6 mm or 1.2 mm was heated up to 900°C for 4 min, it was press formed and simultaneously quench hardened with dies, or water-quenched. Simulated hot-stamping test was also carried out
