The world today sees a dramatic increase in the number of people and the quantities of articleslproductswhich are to be transported.This results in an ever-increasing demand in the steels used in the transportationindustry. Key factors are environmental regulations, safety, and life expectancy and product cost in determiningwhich types steel to use. Especially the ferritic 12 % chromium stainless steels has seen a significant development and usage in recent years. Compared to typical carbon steels high strength/low alley steels and structural steels the 12 “A chromium steels offers improvement in corrosion and wear resistance and weldabilty outlining advantages in light weight constructionand an overall saving. The paper presents the chemical compositionand mechanical properties of grade 4003 which is increasingly used world wide in areas of public transportation, rail transportation, mining
industryand sugar industry,among others. The impact of corrosionand abrasion of this stainless steel versus the standard carbon grades and
cost efficiency are discussed. Keywords:12% chromiumsteel, corrosion,abrasion, transportation,costs.
