Abstract
PURPOSE: To obtain a steel, useful as a pressure vessel, having high strength and toughness, by letting the steel contain specified amounts of C, Si, Mn, Cr, Mo, sol.Al and B.
CONSTITUTION: A steel useful as a pressure vessel is a 3Cr-1Mo steel comprising, by wt%, 0.05W2 C, Si<0.15, 0.8W1.2 Mn, 2.5W3.5 Cr, 0.8W1.2 Mo, 0.005W0.07 sol.Al, 0.00015W0.0015 B and the balance being Fe and inevitable impurities. The steel may contain N<0.006, P<0.01 and B<0.01 in addition to said composition. The steel is especially suitable for a pressure vessel in a petroleum-refining industry, which is used over a long period under a severe use condition.
