The press hardening steel with thick specification has been used as automobile chassis parts. With the increase of the thickness, the cooling rate of the inner core is lower in the conventional process, resulting in a poor harden ability, and the fatigue test is not qualified. In this study, the microstructure of hot forming parts with thick specifications was studied by means of metallographic and micro-hardness testing. The results show that there is a microstructure gradient in the thick hot forming parts, which leads to the uneven strength in the cross section and finally affects the fatigue test results.The finite element analysis method is used to study the cooling rate of the inner core of the hot forming parts. The high hardenability press hardening steel products has been prepared by adjusting the components.

Energy and resource efficiency is a pressing issue for technological markets in the 21st century. In the field of production technology the development of energy and resource efficient processes and process chains is of particular importance. In order to meet these needs sustainable methods and standards have to be developed. This paper presents a new procedure to calculate and evaluate the energy and resource efficiency of process chains. The method consists of 4 stages that proceed from the real world to the quantitative calculation and qualitative evaluation of material and energy flows. The method is explained and validated using press hardening process chains as an example. The procedure enables the user to systematically capture and structure the press hardening process chain and subsequently develop a comprehensive model of the whole process chain. As a result, it allows to calculate the energy requirements for each stage of the process chain, and later on the process chain as a whole. The intention of the developed procedure is to provide a tool to detect the most energy efficient variant from a range of possible process chains.

EuroCarBody, offer the most important forum for defining and discussing the state of the art in modern series car body engineering. The present paper concerns the materials of press hardened steels and its’ manufacturing technology (Hot stamping) applied on vehicle on EuroCarBody from 2009 to 2013 through presentations and benchmark datas. The using percentage of press hardening steels (PHS) on body in white (BIW) are summarized and analyzied. It can be noted that the number and weight of BIW parts using of press hardening steels are increasing from 2009 to 2013, some kind of vehicle, such as Audi A3, the using percentage of PHS reaches 21.6%. The press hardening steels have started used on commercial vehicle from EuroCarBody 2013. More and more new technologies applied on hot stamping processing, such as Joule heating for hot stamping, Hot-form-process partial tempering, Tailor Rolled Blank (TRB) technolgy, etc. With the developing of the automotive industry, more and more hot forming parts will be applied on vehicles in the future.
