Abstract
PURPOSE: To provide the title steel consisting of a respectively specified amt. of C, Si, Mn, Cr, Cu, Mo, V, Ni, sol. Al and N, and the balance Fe and impurities and having superior hot pipe formability and high tensile strength by restricting P, As, Bi, etc. out of the impurities.
CONSTITUTION: This steel consists of C 0.3W0.45%, Si 0.1W0.5%, Mn 1.3W2%, Cr 0.6W1.5%, Cu 0.2W0.5%, Mo 0.15W0.5%, V 0.05W0.4%, Ni 0.3W0.8%, sol. Al 0.01W0.08%, N 0.002W0.02%, and the balance Fe and impurities. Out of the impurities P and As, Bi, Sb or Sn are restricted to 0.025% or less and 0.003% or less, respectively. Tis steel can be formed into a high tensile steel pipe having a tensile strength of 95W120kg/mm2 by a piercing type manufacturing method of a low cost. Since the Ni content has been saved considerably, the pipe manufacturing cost can be reduced.
