ABSTRACT
The need to search for oil and natural gas in more sever environments, including both arctic and deep-water regions, resulted in Customer specifications that require increased strength and toughness, as well as, heavier-wall seamless pipe products. To meet these demands, tubular manufacturers usually use a combination of chemistry modifications, namely increased alloying elements, and thermomechanical-processing techniques (TMCP) to achieve the desired customer requirements. The present study addresses the use of a TMCP processing practice as well as the addition of vanadium and columbium to enhance the mechanical property requirements of an API Specification 5L Grade X70 quenched-and-tempered heavy wall seamless pipe.

BIO
Riad Asfahani is a senior research engineer for U.S. Steel Research and Technical Center in Munhall, PA., where is responsibilities include the development of new low-carbon steel grades through microalloying and thermomechanical processing for improved toughness and weldability. Among his technical achievements at U.S. Steel, Asfahani co-developed a low-carbon weathering steel grade with a low yield-tensile ratio that meets the Federal Highway Administrationís Bridges of the Future program requirements.

Prior to joining U.S. Steel in 1990, Asfahani was a senior development engineer with Cabot Corporation, a research engineer with Reading Technology and a process engineer with Tubular Products Division. He receives his B.S. in metallurgy from Western Michigan University and his M.S. in metallurgy from the University of Notre Dame.

A Fellow of ASM and current chair of the Events Committee, Asfahani is a past chair of the Technical Programming Board and a past member of the Events Committee. He has served as chairman of the Pittsburgh Golden Triangle Chapter and participated in development of the ASM Strategic Plan.
