The mechanical and corrosion performance of low alloy steel tubular goods depends on the microstructure obtained as a result of the combination of alloying elements and manufacturing process parameters. The basic design philosophy for the selection of the alloying elements is ruled by the balance between the steel cost and the material *** this approach the alloying sequence for the manufacturing of tubular components in oil country tubular goods(OCTg) application is generally Mn,C,r and Mo,used as substitutional elements in a total added weight concentration around 1%up to 3%.Other elements such as B,Ti,Nb and V are applied as strengthening microalloying elements forming fine precipitates. A lack of experience is found related to the use of Tungsten(W) on OCTg applications,although W is also a substitutional element that belongs to group 6 of the periodic table together with Cr and *** the other hand W is widely added for steel pipes working in high temperature services such as power plant boilers,where creep resistance is *** is also applied for tool steels enhancing the hardness,wear resistance and cutting performance. Taken into consideration the similarity between Cr,Mo and W and the applications where W has been proven it was decided to analyze the feasibility of using W as an alternative alloying element for some OCTg applications. Another factor that drives this study is the fact that W could be a cost effective substitute of Mo,depending on the alloy market price. This paper is based on literature review and experimental activity done on laboratory steels in which 0.1%Mo was replaced by 0.2%and 0.4%*** different findings in regards with manufacturing process considerations, material performance and the possible use of W alloyed steel for OCTg applications are summarized. (1 ) Opposed to the susceptibility shown by low carbon with high Cr-W content,hot cracks are not expected in medium C steels(0.2%-0.3%) with W addition up to 1%.
