71 rows · The supply of steel in the oil and gas industry is critical. Steel is used in all Strengthening Low Carbon Steels for Oil and Gas Spiral
Oct 02, 2008 · Strengthening mechanisms applied for modern line pipe steel design were studied. Low carbon steels alloyed with Mn, Mo, V, Nb processed by the way of controlled rolling were developed for spiral welded X65-X80 line pipes up to 1420 mm diameter. Formation of the microstructure during steel processing was studied.
