Study on the Ferrite stainless steel 4003 made in Germany

Zhang Zhi-chang

Abstract

New type of Ferrite Stainless Steel 4003 is used more widely on the vehicle.It becomes more important to research the weld behavior for the manufacture of the freight train.By the plasma cutting and MAG welding tests,it could find that the microstructure of the heat affected zone(HAZ) is finer than that of the HAZ of the TCS material made in China.At the same time,the impact tenacity of the HAZ of the Ferrite Stainless Steel 4003 joints is higher than that of TCS material.The reason is that Ti content in 4003 is higher than that in TCS,which cause the microstructure more fine for the TiC and TiN dispersive distribution.
