Impact of Nb Microalloyed Press Hardening Steels on the Passive Safety of Modern Vehicles
Introduction In order to catch up with the international standards on safety and CO2 emission,local OEMs in China haveincreased use of high strength steel from 30％ to 50％ in average in the body-in-white of new vehicles over thelast five years.To speed up this process,CBMM and CITIC Metal have been facilitating Early VendorInvolvement Program (EVI) in China (also globally) by strengthening vertical collaboration between partnersof the whole supply chain.In this process OEMs and T1 suppliers involve the steel suppliers at an early stageof the product development process so that they can develop and optimize high strength steels with enhancedproperties according to the specific requirements of downstream customers,for example,stable and uniformmechanical properties at high strength level,specific formability tailored for different forming processes(elongation vs.hole expansion),good welding behaviour under different welding conditions and finally thecrashworthiness required by OEMs for the enhanced passive safety in the event of crash.
