Coating steel sheet for fuel tank which does not contain hazardous substances, durable for FAME (Fatty Acid Methyl Ester), possesses longer useful life has been demanded. ECOKOTE-S has been developed by modifying coated layer's structure of ECOKOTE-T, having finely dispersed zinc, attributed to superior corrosion resistance. ECOKOTE-S has pressing, welding and painting ability equivalent to existing materials, contributing to widely adoption by domestic and foreign automotive manufacturers. Source

Application of ultra-high strength steel sheets is one of the most important methods to satisfy weight reduction and crash safety of a vehicle. Recently, there is a trend to apply ultra-high strength steel sheets widely to auto-body parts. In this report, present situation of ultra-high strength steel sheets, especially with tensile strength more than 980MPa and 1,470MPa by hot-stamping, have been introduced. Source

The application of high strength steels to car body structure has been accelerated for improved crashworthiness and light weight body. In order to use effectively diversified materials, the importance of numerical simulation and experimental techniques for crash properties of parts and structures has been increased. Here, an overview of a comprehensive approach for materials and structure optimization is presented, by introducing developed technologies for energy absorbing property evaluation and failure behaviour prediction.
