Abstract

A process for manufacturing a vehicle part from steel material, such as Mn22B5 steel material, using a single transfer press is provided. The process includes stamping, trimming, and piercing the steel material in the transfer press at room temperature, before the steel material is heated. The process then includes induction heating of the stamped steel material in the same press to form austenite in the steel material. After the induction heating, the process includes rapid quenching of the steel material in the same press to form martensite in the steel material. The process does not require an oven to heat the steel material prior to stamping and does not require laser machines for the trimming and piercing. The steel material does not need to be transferred to multiple different locations, which contributes to the improved productivity of the process compared to conventional hot stamping processes.
