Abstract: As the biggest steel tube consumer, the U.S. has its 30% steel tubulars and 80% stainless steel seamless tubes imported from abroad. Detailed analysis is made on the main aspects of U.S. steel tube market and stainless steel tube market, including the supply-demand situations for different types of steel tubes, self-made product proportion, import and export situation as well as the proportions of welded steel tubes and seamless steel tubes, etc. Then it is pointed out that the domestic development of stainless steel tube production should fo- cus on enhancing the proportion of hi-grade welded tubes, expanding production of the sought-after weld tubes and developing new types of hot-rolled seamless tubes.
