摘要： The present application describes a steel composition that provides enhanced corrosion resistance. This steel composition includes one of vanadium in an amount of 1 wt % to 9 wt %, titanium in an amount of about 1 wt % to 9 wt %, and a combination of vanadium and titanium in an amount of 1 wt % to about 9 wt %. In addition, the steel composition includes carbon in an amount of 0.03 wt % to about 0.45 wt %, manganese in an amount up to 2 wt % and silicon in an amount up to 0.45 wt %. In one embodiment, the steel composition includes a microstructure of one of the following: ferrite, martensite, tempered martensite, dual phase ferrite and martensite, and dual phase ferrite and tempered martensite. Further, the present application describes a method for processing the steel composition and use of equipment such as oil country tubular goods, fabricated with the steel composition.
